BAT1,1,Adafruit,2011 / PKCELL 803860 protected pack,https://www.adafruit.com/product/2011,https://cdn-shop.adafruit.com/datasheets/LiIon2000mAh37V.pdf,MECHANICAL CANDIDATE; charging temperature mismatch,1S 3.7 V 2000 mAh; 4.2 V charge; 2 A maximum discharge. Manufacturer maximum dimensions include PCM; retail headline is smaller. Cell charge range 0–45 C; existing direct 103AT TS window approximately 0–50 C must be corrected/qualified before battery charging.
BAT_EXT,1,Adafruit,3814,https://www.adafruit.com/product/3814,https://www.adafruit.com/product/3814,Stock 200 mm male PH2-to-wire pigtail; confirm delivered lead gauge/polarity,Replaces 500 mm 1131 extension. Factory male PH2 header mates the unchanged battery plug; opposite end is supplied as bare wires. Trim/strip free ends for WAGO; no extra connector or custom battery adapter. Model uses 0.9 mm lead OD as a fit assumption; verify delivered insulation/current rating.

SW_LEADS,1,Adafruit,1152 (10 pairs; use 2 pairs),https://www.adafruit.com/product/1152,https://cdn-shop.adafruit.com/datasheets/quickconnect110.pdf,Stock precrimped leads; equivalent terminal drawing only,"0.110 inch quick-connect female sockets, 200 mm 22 AWG leads. Keep quick-connects; cut off opposite JST connector, trim and strip for WAGO. Drawing linked by supplier is an equivalent terminal, not a guaranteed TE terminal identity."
BASE_SPLICE,5,WAGO,222-412,https://www.digikey.com/en/products/detail/wago-corporation/222-412/13549446,https://www.wago.com/us/wire-splicing-connectors/splicing-connector/p/222-412,Stock 2-wire single-potential lever splice,"One block EACH for VBAT, NTC sense, NTC dedicated return, ASK_REMOTE and PWR_REMOTE. 28–12 AWG; strip 9–10 mm; ONE potential per entire block, never two different nets.

Do not tie SPK_N here. Do not replace with 221 without checking minimum wire size."
SPK1,1,Same Sky,CES-30207-158L120-67,https://www.sameskydevices.com/product/resource/ces-30207-158l120-67.pdf,https://www.sameskydevices.com/product/resource/ces-30207-158l120-67.pdf,Already ordered; retained,"8 ohm 1.5 W, nominal body 30 x 20 x 7. 120 +/-5 mm supplied 30 AWG lead and Molex 51021-0200 female connector. Do not cut supplied speaker cable. Limit amplifier power in firmware."
SPK_EXT,1,Molex,2181130204,https://www.newark.com/molex/218113-0204/cable-assy-2pos-rcpt-plug-425mm/dp/66AJ9504,https://www.molex.com/content/dam/molex/molex-dot-com/products/automated/en-us/salesdrawingpdf/218/218113/2181130204_sd.pdf,Catalog 425 mm preassembled PicoBlade plug-to-socket cable; check delivery at order,"Keep male 51047 speaker end. Cut off opposite female connector, thread 28 AWG wires through neck, then fit XH contacts at head. Modeled run fits within 425 +/-8 mm. Determine speaker polarity by continuity: vendor drawing crosses cavity numbers. Stock cable needs head-end termination, no extra base splice. DigiKey US page currently shows zero stock; Newark lists UK-stock delivery."
NTC1,1,Semitec,103AT-11,https://www.digikey.com/en/products/detail/semitec-usa-corp/103AT-11/16578928,https://www.semitec-global.com/uploads/2022/01/P12-13-AT-Thermistor.pdf,Stock factory prewired thermistor; new sourcing option replaces bare 103AT-2 in this model,"10k ohm 1%, B25/85 3435 K 1%, matching the old nominal electrical curve. Factory insulated parallel leads 600 +20/-0 mm; trim/split/strip into separate WAGO sense/return blocks. No custom thermistor solder joints. Protected body 15 mm maximum length x6.2 width x5 thickness, mounted at cell side. Lead OD1.8 mm is a conservative fit assumption; confirm shipped cable. Mounting/thermal response still need qualification; battery 45 C versus current approximately50 C hot cutoff hold remains. Already-owned 103AT-2 remains usable only with a prepared insulated extension; not the minimum-soldering version shown."
