LilyGo TTGO T-OI Plus ESP32-C3 CH9102F Development Board
The LilyGo T-OI Plus is a compact development board with the ESP32-C3 (RISC-V, 160 MHz), Wi-Fi and Bluetooth 5 (LE). It is programmed and powered via USB-C and the CH9102F USB-to-serial chip. A battery holder for a 16340 cell can be mounted on the back; the TP4054 charging circuit charges the cell via USB.
Important: The charging circuit charges the inserted cell. Therefore only insert a rechargeable 3.7 V 16340 Li-ion cell and no CR123A lithium battery. Battery holder and cell are not included.
