LILYGO TTGO T-OI Plus ESP32-C3 RISC-V MCU Wireless Module Development Circuits Board Suppert Wi-Fi Bluetooth B-N33R

T-OI PLUS is based on the ESP32-C3 main control chip, which is a safe, low-power, low-cost RISC-V MCU.

Supports Wi-Fi and Bluetooth 5 (LE).

It has rich memory resources and can meet the functional requirements of various common IoT products.

It continues the appearance and structural design of the T-OI ESP8266 version. It is based on the pin interface compatible with the MINI D1 expansion shield, and is equipped with a 16340 lithium battery holder. It is also compatible with the Grove interface, which is convenient for direct expansion of existing mini D1 expansion shields and Grove interface modules.
