Product Description

T-OI As the name suggests, T is still our T series. TOI is from the right to the left, meaning IOT products. This product uses IOT ESP8266. Features 1. Added 16340 electrical socket to the ordinary development board, which can use the corresponding rechargeable 16340 battery to power the system, which is convenient, beautiful and practical. 2. The product is compact and the size design extends the size design of this battery holder. 3. All IO ports are reserved from both sides, compatible with the distance between MINI D1 extended version and breadboard. Grove interface is reserved at the same time, compatible with Grove interface module, and T-Watch r module (T-Watch special connection cable needs to be connected). 4. We will design more convenient expansion modules to match the motherboard to facilitate the realization of various ideas for learners.
