Specification: Origin: Mainland China Type: Module Condition: New Wifi: Supports IEEE 802.11 b/g/n protocol Supports 20 MHz bandwidth in the 2.4 GHz band Bluetooth-compatible: Bluetooth-compatible low energy subsystem supporting BT 5 CPU and storage: 32-bit RISC-V single-core processor up to 120 MHz with 272 KB SRAM (16 KB dedicated to cache) and 576 KB ROM storage Advanced peripheral interfaces and sensors: 13 GPI0 ports Digital interface. 3x SPI 2x serial port 1 x I2C master LED PWM controller, up to 6 channels General purpose DMA controller (GDMA), 1 receive channel and 1 transmit channel Analog interface. 1x12-bit SAR analog/digital converter, up to 5 channels Operating temperature: -40°C to 105°C Product size: 31.00x26.00x3.00mm/1.22x1.02x0.12inch product description ESPC2-12 is designed based on Espressif ESP8684, an extremely low-power SoC equipped with RISC V 32-bit single-core processor, and supports IEEE 802.11b/g/n (2.4GHz WiFi) and Bluetooth-compatible 5 (BLE) modules. How to enter the program GPI09 can be input as long as it is connected to low ground. After the input is completed, cancel the grounding, otherwise it will not work. Note: 1. The ESP8684 RF instantaneous current can reach 400~500mA, so the minimum power supply requirement is 500mA. 2. Based on the 500mA power supply requirement, it is recommended that the power and ground traces be no less than 30mil. It is recommended to drill 2 to 3 via holes for power lines to prevent PCB production line deviation. 3. In order to obtain better radio frequency performance, it is recommended that no parallel wiring be allowed near the PCB antenna, and that the download interface should reserve a pad away from the antenna. 4. It is recommended to wipe the module clean before downloading the program, otherwise some parts may not be able to start. 5. If the module cannot start normally and keeps restarting, it is recommended to check the power supply, including power input, power trace width, pass-through, power trace, diode cascade power supply, etc. 6. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! 7. Please allow 1-2cm measuring deviation due to manual measurement. Included: 1 x development board 1.
