| Q1-Q3 | FS8205A | |
| U1 | GD25Q128ESIG | |
| U2 | TPS61023DRLR | Synchronous boost converter, 0.5-5.5 V in, 2.2-5.5 V out, 3.7 A typ / 2.7 A min valley current limit, 1 MHz, internally compensated, SOT-563 (DRL0006A) | TI TPS61023DRLR | LCSC C919459. Symbol geometry imported verbatim from the Ultra Librarian KiCad v6 export (2026-07-26). Base-station V_LORA boost, replaces LM5157QRTERQ1, rail retargeted 7.49 V -> 4.95 V via a 732k/100k divider (TI datasheet Fig 8-1 values). NOTE: Ultra Librarian types SW and VOUT as power_in; VOUT is really an output, so ERC will want a PWR_FLAG on V_LORA unless that pin type is changed to power_out. |
| U3 | ESP32-S3RH2 | |
| U5 | BQ21040DBVR | 1-cell, 0.8-A Li-ion and Li-polymer battery charger |
| U9 |
