Hardware Overview

The hardware platform of this project is the WINC1500 Secure Wi-Fi Board. User can get this board in Master Conference 2018 or from Microchip FAE.

The WINC1500 Secure Wi-Fi Board is controlled by an SAML21G18B host MCU. It is equipped with a WINC15x0 IEEE 802.11 b/g/n network controller, an ATECC608A CryptoAuthentication™ device, an MCP73833 Li-Ion/Li-Po charge management controller, a MIC5317 High PSRR LDO, BME280 environment sensor, VEML6030 light sensor and BHI160 motion sensor.

Power supply
The board can be powered up by USB power or TR14500 lithium (3.7V) battery.
Jumper J6 is used to select the power source.\

Short the jumper in red circle below for USB power

Short the jumper in blue circle below for lithium battery source. Lithium battery can be charged up by USB power. LD1 show the charging status.

CAUTION: Overcharging is not recommended as the package does not include the rechargeable battery and the board does not undergo the overcharging test.
