IMPR-POW-C-02
Breadboard-compatible power, charging, UART, and protection in one module.
- 01 5 V enters through USB-C and powers the load directly.
- 02 The TP4056 charges the cell while the DW01A guards it.
- 03 Unplug USB and the load switches to the battery automatically.
- 04 The CP2102 gives the host serial access for flashing and diagnostics.
