describe

WT32C3-S1 and WT32C3-S2 are general-purpose Wi-Fi and Bluetooth LE (Bluetooth LE) modules, which are low-power and cost-effective embedded wireless network control modules. It can meet the needs of IoT applications such as smart grid, building automation, security, smart home, and telemedicine. Both WT32C3-S1 and WT32C3-S2 modules are equipped with 4 MB external SPI flash. WT32C3-S1 adopts PCB onboard antenna, WT32C3-S2 adopts connector to connect external antenna. The WT32C3-S1 and WT32C3-S2 modules use the ESP32-C3 chip. The ESP32-C3 chip is equipped with a RISC-V 32-bit single-core processor, and the main frequency supports up to 160MHz. The module supports the standard IEEE802.11 b/g/n protocol, Bluetooth low energy 5.0 (Bluetooth LE): Bluetooth 5, Bluetoothmesh. Users can use this module to add Bluetooth distribution and networking functions to existing devices, or to build an independent network controller.
