flashtree 2Pcs ESP8266 ESP-01S WiFi Serial Transceiver Module with 1MB Flash for Arduino

SKU 00506

The ESP8266 Serial-to-WiFi adapter created by Espressif has seen a wide adoption as a cost-effective solution for IoT and WiFi-capable devices. This tiny-sized System On a Chip (SoC) includes an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) as well as a full TCP/IP stack with DNS. Because the ESP8266 comes only in a Surface-Mount package, a few different vendors have developed modules labeled ESP-NN where NN are numbers ranging from 01 to 13 (at the time of this writing).Although most ESP-NN modules are intended to be mounted on a PCB via castellated pins, the ESP-01 includes a set of 0.1in-spaced female pins that can be used to easily connect it to a solderless breadboard! Please note that because the ESP8266 doesn't have a native USB interface, all ESP-NN modules need an external USB to Serial adapter (e.g., FTDI FT232 USB to Serial UART adapter) to receive data from a computer's USB connection.Features: 6 GPIO (save for D0, every GPIO can be PWM, I2C (software), 1-wire) ESP-01 Wi-Fi module containing the ESP8266 IC PCB-mounted antenna Integrated TCP/IP protocol stack 8-pin female header socket product Product Features: Supported protocols: 802.11 b/g/n Serial/UART baud rate: 115200bps Input voltage: 3.3V Max I/O voltage: 3.6V Regular operation current draw: ~70mA Current draw (peak): ~300mA Power-down leakage current: <10µA Output power: +19.5dBm (802.11b) WiFi security modes: WPA, WPA2 Module's dimensions: 24.75mm x 14.5mm (0.974" x 0.571") ee Packing Listing: esp-01 ESP8266 MODULE * 1
