Main PCB marking: KCE210119
Smart, module based design. BLE MCU marked with YC1063 UG6860. Possibly YiChip YC1063 Many thanks to David for the tip! Two (supposedly H bridge) SOT-23-2 marked with SA1016 (U2 and U6). Lipo charger marked with B137 70pJ.
Battery has 100 mAh printed on it and it is supposed to be a Huahui HFC1025 LiFePo4? single cell. ]]>Weelye RX16 SPI log
