HKD TTGO T-OI Plus ESP32-C3 Dev Board RISC-V WiFi Bluetooth with Battery

The HKD TTGO T-OI Plus is a compact and versatile development board built around the ESP32-C3 chip, a secure and energy-efficient RISC-V microcontroller designed for IoT and wireless applications. With integrated Wi-Fi (IEEE 802.11 b/g/n) and Bluetooth 5 (including LE and mesh support), this board offers robust wireless connectivity for a wide range of projects.

Equipped with 4MB of Flash memory and a 16340 battery holder (optional with/without battery slot), the T-OI Plus supports portable, low-power applications. Its 32-bit RISC-V CPU runs at up to 160MHz and includes 400KB SRAM, 384KB ROM, and 8KB RTC memory, providing reliable performance for embedded systems and prototyping.

For hardware interfacing, the board includes multiple communication and control options such as 3x UART, I C, I S, PWM, TWAI (CAN bus), RMT, timers, and full-speed USB serial. A Grove-compatible 4-pin (2.0mm) connector expands flexibility, making it easy to integrate sensors, actuators, or additional modules.

Ideal for developers, hobbyists, and engineers, the T-OI Plus offers an affordable platform for building Wi-Fi-enabled devices, Bluetooth mesh networks, smart controllers, and portable IoT systems.
