TTGO T-OI Plus ESP32-C3 RISC-V Board with 16340 Battery Holder

The TTGO T-OI Plus is a compact development board powered by the ESP32-C3 32-bit RISC-V microcontroller with integrated Wi-Fi and Bluetooth 5 connectivity. Featuring an onboard 16340 battery holder and a Grove connector, it provides an efficient platform for portable wireless IoT projects. It is well suited to students, makers, and hobbyists developing connected applications.

RISC-V processing and wireless control

The board is driven by an ESP32-C3 32-bit RISC-V processor clocked at 160MHz with 400KB of SRAM, 384KB of ROM, and 4MB of flash storage. It provides wireless communication with support for IEEE 802.11 b/g/n Wi-Fi along with Bluetooth 5 and Bluetooth mesh.

Onboard battery holder and expansion

An integrated 16340 (CR123) battery holder enables convenient standalone and portable operation. The board also features a 4-pin 2.0mm Grove connector for straightforward hardware expansion.

Peripheral interfaces

Built-in peripheral interfaces include 3x UART, I2C, I2S, LED PWM, TWAI, Timers, RMT, and full-speed USB Serial.

Battery notice

Please note that the 16340 battery is not included and must be acquired separately.
