The steering is similar (dc motor without end limits):
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. ]]>http://users.atw.hu/balubati/blog/index.php?entry=entry211213-2308082021-12-13T00:00:00Z2021-12-13T00:00:00ZWeelye RX16 SPI loghttp://balubati.atw.hu/website_files/we ... .logicdata
