### H.1 TI BQ2970x (datasheet SLUSBU9I, Mar 2014 rev Aug 2024) — VERIFIED
Source: https://www.ti.com/lit/ds/symlink/bq2970.pdf (downloaded via curl; the bq29700 symlink returns an HTML stub)
- Package DSE = WSON-6, 1.50 x 1.50 x 0.75 mm. Pinout (top view): 1 NC, 2 COUT (charge-FET gate drive), 3 DOUT (discharge-FET gate drive), 4 VSS, 5 BAT (VDD), 6 V- (charger-negative / current-sense input). Input range pack+: VSS-0.3 V to 12 V; V- abs max BAT-28 V.
- Variant table (OVP V / OVP delay s | UVP V / UVP delay ms | OCC V / delay ms | OCD V / delay ms | SCD V / 250 us):
  - BQ29700: 4.275 / 1.25 | 2.800 / 144 | -0.100 / 8 | 0.100 / 20 | 0.5
  - BQ29701: 4.280 / 1.25 | 2.300 / 144 | -0.100 / 8 | 0.125 / 8  | 0.5
  - BQ29702: 4.350 / 1    | 2.800 / 96  | -0.155 / 8 | 0.160 / 16 | 0.3
  - BQ29706: 3.850 / 1.25 | 2.500 / 144 | -0.150 / 8 | 0.200 / 8  | 0.6
  - BQ29707: 4.280 / 1    | 2.800 / 96  | -0.090 / 6 | 0.090 / 16 | 0.3
  - Recovery delays: OVP 12 ms; UVP/OCC/OCD 8 ms. OVP release hysteresis 100 mV (and VSS-V- > OCC(min)); UVP release +100 mV hysteresis with (BAT-V-) > 1 V. tSCD fixed 250 us +/-50%.
- Current: INORMAL 4 uA typ / 5.5 uA max (BAT 3.8 V, V- 0 V); IPower_down 0.1 uA max (BAT = V- = 1.5 V). IV-S sink on V- 8-24 uA.
- Reference schematic (TI Fig. in section 9): cell+ --R1 330 Ohm--> BAT(5); C1 0.1 uF BAT-VSS; VSS(4) = cell-; R2 2.2 kOhm from V-(6) to PACK-; DOUT(3) -> gate of DSG N-FET (source to cell-), COUT(2) -> gate of CHG N-FET (source to PACK-), FET drains tied together (common-drain dual N-MOSFET); TI recommends 5 MOhm gate-source bleed on each external FET; "the 330 Ohm resistor also limits the current during a reverse connection". TI's 7 A design example uses CSD16406Q3 (7.5 mOhm); for a 0.5 A tracker pack a dual SOT-23-6/TSSOP-8 device is adequate (see H.6). OCD trip current = VOCD / (Rds_CHG + Rds_DSG): with two 25 mOhm FETs (FS8205A @4.5 V) -> ~2.0 A; at 35 mOhm each (Vgs 2.5 V) -> ~1.4 A; comfortably above 0.5 A LTE-M bursts.

Reputable choice: TI BQ29700DSER (C183096; OVP 4.275 V, UVP 2.80 V, OCD 100 mV/20 ms, SCD 0.5 V/250 us, 4 uA) + FS8205A dual N-FET (C2830320, or AO8810 C21426 for lower Rds). Reference schematic: R1 330 Ohm cell+ -> BAT, C1 0.1 uF BAT-VSS, R2 2.2 kOhm V- -> PACK-, DOUT -> DSG gate, COUT -> CHG gate, FET sources to cell- and PACK-, drains common; add 10 k NTC (NCP15XH103F03RC, C77131) and pack-ID resistor to the 4-pin pack connector. If cost dominates, DW01A + FS8205A (both >49k in stock, <$0.11 total) with C1 0.1 uF.

## J. Battery pack ID-resistor (BSI) scheme — VERIFIED
- Nokia 2630 (RM-298) service manual, Battery Interface page: BSI is an analog input read by the phone ADC; the phone has "a 100 kohm pull up to 2.78V (VBB1)"; the pack contains "a fixed resistor" whose value "indicates type and default capacity of a battery". https://www.manualslib.com/manual/851543/Nokia-2630-Rm-298.html?page=165
- EDN "Mobile phone battery emulator": BSI pull-down values — BL-5CT (1,090 mAh) 82 kOhm; BLB-2 (650 mAh) 68 kOhm; BLC-2 (900 mAh) 75 kOhm; BL-4U (1,110 mAh) 91 kOhm. https://www.edn.com/mobile-phone-battery-emulator/
- Design note: with nPM1300 there is no dedicated BSI input; use a spare nRF9151 ADC pin with a 100 k pull-up to a switched rail and E24 values (e.g. 47 k = 600 mAh, 68 k = 800 mAh, 91 k = 1000 mAh), and keep the NTC on a separate pin.

### B.1 Land patterns (from drawings)
- KLS1-SIM-066 (recommended PCB layout, tol +/-0.05): six signal pads 0.75 wide x 2.00 long on 1.27 mm pitch (5 x 1.27 = 6.35 between outer pad centres; 7.30 outer edge span), pad row 1.20 in from the pattern edge with 0.95/0.65 edge offsets; two locating holes 2 x dia 0.75 on 8.50 spacing, 12.00 from the pad row (12.29/12.99 pattern width, 4.10 total to eject stop); four shell pads 4 x 2.10 long; card-lock position 1.00, push stroke 0.30, eject travel 4.10. Ratings 0.5 A, 5 V AC/DC, 100 mOhm, -40..+85 C, 3,000-8,000 insertions, CD normally short / open with card.
- XUNPU SMN-303: signal pads 6 x (0.70 x 1.30) on 1.27 pitch (span 6.35), CD pad 0.70 x 1.85 offset 0.80, shell pads 2 x (1.14 x 2.10) and 2 x (0.75 x 1.25) at the rear corners (8.50-8.56 apart), pattern envelope 13.48 mm long; push stroke 0.65 +/-0.3, card-lock 1.50 +/-0.3, eject 4.20 +/-0.5 (card protrudes 4.2 mm for removal). Ratings 30 VAC, 0.5 A, 50 mOhm, 1000 MOhm, 500 VAC/1 min, -25..+85 C.
- Wurth 693043020611: 6 pads 0.65 x 1.30 on 1.27 pitch (6.35 span, 3.18 to centre), 4 shell pads 0.48 x 1.80 at 12.14 x 6.42/4.42 offsets, 1.00 x 1.03 corner pads, body 9.4 x 12.5 x 1.2 mm.

### B.2 Recommendation
Sealed consumer device -> push-push with card detect: XUNPU SMN-303 (C266888) primary (110k in stock, $0.49, 1.37 mm, CD switch); SHOU HAN "NANO SIM 7P H1.37" (C7529384, 13.72 x 12.29 x 1.37, $0.29) as alternate; KLS1-SIM-066 is the same class but not JLC-stocked. If the SIM is installed once in the factory, the push-pull SMN-304 (C266889, 1.35 mm, $0.22) is the cheapest/most stocked but has no detect switch. Smallest footprints are the push-pull Wurth 693043020611 (12.5 x 9.4 x 1.2) and GCT SIM8055 (12.2 x 9.54 x 1.35), neither at JLC.

## G.12 Cell recommendation
- Rated 1C continuous AND 2C pulse: only Honcell HCP503040 (2.0C = 1.2 A for 3-4 ms bursts) states a pulse rating. 1C continuous only: Jauch LP503040JH, LiPol LP513040/LP503040, LiPol LP603450, Renata ICP622540PMT, SparkFun DTP603443 (850 mAh), PKCELL LP603040 (750 mAh), Ufine 503040. EEMB LP603450HA is a 10C bare high-rate cell (no PCM). A 0.5 A LTE-M burst is 0.83C on 600 mAh, 0.67C on 750 mAh, 0.59C on 850 mAh — all inside 1C, so the pulse rating is not the limiting factor; ESR is (Honcell cell+PCM 240 mOhm -> ~120 mV droop at 0.5 A).
- PRIMARY: Honcell HCP503040NFC (600 mAh, PCM S-8261+8205 with 10k NTC, Molex 51021-0300, 5.4 x 30.5 x 40.5 mm, 14.5 g, UL1642/IEC62133/UN38.3/KC/CE claimed) — the only candidate with a complete, current (2024) spec incl. 1C/2C ratings and PCM BOM; price/MOQ UNVERIFIED (direct from Honcell). For prototypes buy Jauch LP503040JH+PCM+2wires (DigiKey $10.81, 1,643 in stock, UL1642 + UN38.3, 42 x 30.5 x 5.4 mm) — same 503040 envelope, no NTC.
- ALTERNATE: Renata ICP622540PMT (600/550 mAh, 42.5 x 25.7 x 6.5 mm, 11 g, 1C charge/discharge, PCM 2.8 V UVP + 1.0 A OCP, <=220 mOhm; Mouser ~2,425 in stock per search snippet, price UNVERIFIED) — narrower (25.7 mm) for a slim enclosure. For more margin: PKCELL LP603040 750 mAh (1C, CE/IEC/CB/UN38.3) or SparkFun PRT-13854 850 mAh (DTP603443, 1C, 6.0 x 34 x 43 mm, $13.61).
- ~1000 mAh: LiPol LP603450 1100 mAh + PCM + NTC + Molex (6.0 x 34 x 50 mm, 22 g, 1C, IEC62133) or EEMB LP603449 (UL file MH20555, UN38.3; eemb.store sold out).

Source: JLCPCB-hosted copy of the ST datasheet https://jlcpcb.com/partdetail/STMicroelectronics-LIS2DW12TR/C189624 (st.com was unreachable from this session); register bit layout cross-checked against ST's official driver header https://raw.githubusercontent.com/STMicroelectronics/lis2dw12-pid/master/lis2dw12_reg.h
- Pin map CONFIRMED: 1 SCL/SPC, 2 CS (I2C/SPI select; 1 = I2C, internal pull-up), 3 SDO/SA0, 4 SDA/SDI/SDO, 5 NC ("can be tied to VDD, VDDIO, or GND"), 6 GND, 7 RES ("connect to GND"), 8 GND, 9 VDD, 10 VDD_IO, 11 INT2, 12 INT1. Package LGA-12 2.0 x 2.0 x 0.7 mm (Figure 18). Vdd 1.62-3.6 V, Vdd_IO 1.62 V to Vdd+0.1 V.
- Land pattern: the datasheet contains only the package outline (Fig. 18 is an image, no pad table in text); ST's recommended LGA land pattern lives in TN0018 (not fetchable here) -> UNVERIFIED; use the CAD footprint from the JLCPCB/EasyEDA library for C189624 or ST TN0018.
- Decoupling (DS section 4.2): "Power supply decoupling capacitors (100 nF ceramic, 10 uF aluminum)" as close as possible to pins 9 (Vdd) and 10 (Vdd_IO); Vdd may be removed while Vdd_IO stays without blocking the bus.
- I2C: "When using the I2C, CS must be tied high (i.e. connected to Vdd_IO)"; SA0 high -> SAD 0011001b (0x19; 8-bit 0x33/0x32), SA0 low -> 0011000b (0x18; 0x31/0x30) (Table 17). Internal pull-ups on CS and SDO/SA0: 54.4 k @1.7 V, 49.2 k @1.8 V, 30.4 k @2.5 V, 20.4 k @3.6 V (Table 3); CS pull-up can be disabled with CS_PU_DISC in CTRL2 (21h). Leave SA0 floating (internal pull-up -> 0x19) or tie to GND for 0x18.
- Current (Vdd 1.8 V, FS +/-2 g, Table 1 + power-mode table): High-Performance 90 uA (12.5-1600 Hz); Low-Power Mode 1 (12-bit): 1.6 Hz 0.38 uA, 12.5 Hz 1 uA, 25 Hz 1.5 uA, 50 Hz 3 uA, 100 Hz 5 uA, 200 Hz 10 uA; LP2/LP3/LP4 at 1.6 Hz: 0.45 / 0.55 / 0.65 uA; at 12.5 Hz: 1.6 / 2.5 / 4 uA; Power-down Idd_PD 50 nA. Lowest-power wake-up configuration = LP mode 1 at 1.6 Hz (0.38 uA) or 12.5 Hz (1 uA); the activity/inactivity function auto-switches to 12.5 Hz LP on sleep.

| Bosch BMA400 | C437655 | LGA-12 2.0x2.0x0.95 | VDD 1.72-3.6 V, VDDIO 1.2-3.6 V | 3.5 uA (normal, OSR=0); 14.5 uA (OSR=3); "<1 uA and auto-wakeup" low-power mode (DS features) | 160 nA (sleep) | 12-bit | 5,104 | 2.4127 | https://www.bosch-sensortec.com/media/boschsensortec/downloads/datasheets/bst-bma400-ds000.pdf |
Verdict: LIS2DW12 is the cost/availability winner at JLC ($1.16, 33k stock) with 0.38-1 uA motion wake-up; ADXL367 is lowest power (181 nA) but ~$21 and near-zero stock; BMA400 is mid-priced with the richest on-chip motion logic.

## Method notes
- JLC/LCSC stock and prices from https://jlcsearch.tscircuit.com/components/list.json (raw dump in Appendix R1) and LCSC product pages; both were read on 2026-09-14 and differ slightly (LCSC vs JLC-warehouse counts).
- Datasheets were downloaded with curl and text-extracted (pdftotext); image-only drawings (KLS, XUNPU SMN-303, Hirose U.FL, Wurth, pogo pin) were read visually. st.com, analog.com, ti.com/lit/gpn, mouser.com, farnell.com, lcsc.com/datasheet and gct.co were not reachable/blocked from this session, hence the JLCPCB-hosted copies and mirrors cited.
