The ESPC2-12 module adopts the ESP8684 2M chip, which is a universal WIFI and low-power Bluetooth module with powerful functions;<br/>2. The module uses onboard antennas, where Wi Fi and Bluetooth coexist and share the same antenna;<br/>3. Adopting mainstream Type-C interface, it can be used as the power supply for the development board and the communication interface for the ESP8684 chip;<br/>4. The development board is equipped with an extremely low-power SoC with RISC-V 32-bit single core processor, supporting IEEE 802.11b/g/n (2.4 GHz WiFi) and BT 5 (BLE) modules;<br/>5. The development board has rich communication interfaces and GPIO pins, which can support various scenarios and complex applications.</div><br/><p><strong><span style="font-size:20px">Parameter:</span></strong><br/>Development board chip: CH340<br/>ESPC2-12 module chip: ESP8684 (2M)<br/>Module power supply range: 2.8-3.3V<br/>32-bit RISC-V single core processor with a main frequency of up to 120 MHz<br/>Built in 272KB SRAM (16KB dedicated to cache) and 576KB ROM storage space<br/>Supports IEEE 802.11 b/g/n protocol<br/>Supports a bandwidth of 20 MHz in the 2.4 GHz frequency band<br/>Supports 1T1R mode with a data rate of up to 72.2 Mbps<br/>Wi Fi and Bluetooth coexist, sharing the same antenna<br/>Digital interface:<br/>-3 x SPI<br/>-2 x UART<br/>-1 x I2C host<br/>- LED PWM controller with up to 6 channels<br/>- General DMA Controller (GDMA), with 1 receiving channel and 1 transmitting channel<br/>Analog interface:<br/>-1x12 bit SAR analog-to-digital converter with up to 5 channels<br/>-1 x temperature sensor<br/>Timer:<br/>-1 × 54 bit universal timer<br/>-2x watchdog timer<br/>-1 x 52 bit system timer<br/>Product size: 48.4mm * 25.8mm</p><p><strong><span style="font-size:20px">Notes:</span></strong><br/>1. The maximum RF instantaneous current of ESP8684 can reach 400-500A, so the minimum power supply requirement is 500mA. LD0 such as XC6206 and 7533 cannot be used;<br/>2. Based on the power supply demand of 500mA, it is recommended that the wiring between the power and ground should not be less than 30mil. If there are through holes in the power cord, it is recommended to drill 2-3 to prevent PCB production deviation;<br/>3. For better RF performance, please refer to the module placement method in the manual. If there is a certification requirement for the product, it is recommended that there should be no parallel wiring near the PCB antenna, and the download interface should reserve solder pads far away from the antenna;<br/>4. It is recommended to wipe the module clean before downloading the program, otherwise there may be some issues that cannot be started;<br/>5. If the module cannot start normally and keeps restarting, it is recommended to check the power supply, including power input, power trajectory width, path, power trajectory, diode cascade power supply, etc.</p><p><strong><span style="font-size:20px">Instructions for use:</span></strong><br/>Download firmware:<br/>Drop BOOT to LOW level, and then you can download firmware from the ESP download tool software.<br/>How to burn:<br/>As long as GP109 is grounded at a low level, it can be burned. After burning, cancel the grounding, otherwise it will not work.</p><p><strong><span style="font-size:20px">Package include: </span></strong><br/>1X module<br/>2X needle arrangement<br/></p></div></div><br/>
