Specification: ESP8266 CP2102 By exporting all the pins of the ESP8266-12E WIFI module or ESP8266-12F WIFI module, the download program for the ESP8266 WIFI module can be directly developed. With FLASH and RST buttons 11 */O pin 1 * ADC pin Features: Open source, interactive, programmable, low-cost, simple, intelligent, supporting WI-FI Advanced APIs suitable for hardware IO can significantly reduce redundant work in configuring and operating hardware. Nodejs style network API Event driven API for network applications, This helps developers write code that runs in Nodejs style on a 5mm * 5mmsized MCU. Greatly accelerate your IoT application development process. 1. ESP8266 has IO pins 2. No need to download reset Size: 48 * 25 * 10mm/1.88 * 0.98 * 0.39inch ESP8266 CH340 The product is a development board based on Anxinke's ESP12E WiFi module. We have added peripheral circuits to it for easy learning and development. The CH340G serial port chip used in the peripheral circuit has stable performance and is very convenient for debugging. Simply connect it to a computer using an mrico USB cable, and you can download programs for debugging. You can also use specialized software to burn firmware WiFi module parameters: 802.11 b/g/n Passed FCC wireless certification Built in Tensilica L106 ultra low power 32-bit micro MCU, with main frequency support of 80 MHz and 160 MHz, and support for RTOS Built in 10bit high-precision ADC Built in TCP/IP protocol stack Built in TR switch, balun, LNA, power amplifier, and matching network Built in PLL, voltage regulator, and power management components, with an output power of+20dBm in 802.11b mode Aggregation of A-MPDU and A-MSDU and protection interval of 0.4s WiFi @ 2.4GHz, supports WPA/WPA2 security mode Support for AT remote upgrade and cloud OTA upgrade Support STA/AP/STA+AP working mode Support for Smart Config functionality (including Android and for iOS devices) HSPI, UART, I2C, I2S, IR Remote Control, PWM, GPIO Deep sleep maintains a current of 10uA and a turn off current of less than 5uA Wake up, connect, and transmit data packets within 2ms Power consumption in standby mode is less than 1.0mW (DTIM3) Working temperature range: -40 ℃ -125 ℃ Size: 59 * 31 * 10mm/2.32 * 1.22 * 0.39inch ESP8266 WiFi Base Power supply method: 6-24V power supply through DC power socket If you need a compatible NodeMcu Lua WIFI V3 development board, you can purchase it separately Size: 60 * 60 * 10mm/2.36 * 2.36 * 0.39inch Note: 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.
