Maduino Zero ESP8266 Wi-Fi IoT board

Description

Maduino Zero ESP is an IoT (Internet of Things) solution based on the 32-bit SAMD21 microcontroller from Atmel and the ESP-12S Wi-Fi module based on the ESP8266 SoC (System on Chip). It is compatible with the 802.11 b/g/n standard at 2.4 GHz and features an integrated TCP/IP stack, output power of 19.5 dBm, data interface (UART / HSPI / I2C / I2S / Ir Remote Control GPIO / PWM), and a PCB antenna. All pins of the ESP module are available (on two strip connectors), along with a micro SD card slot, I2C interface pins, a micro USB connector for power and PC communication, a 3.7 V input for connecting a lithium polymer battery, a 5 V input for connecting a solar panel to recharge the lithium polymer battery, two status LEDs (for power and battery charging), and a reset button for the SAMD21 microcontroller.

Attention! Except for the STRIP connectors, which must be soldered, the board is supplied already assembled and tested.
