The AE-CLOUD2 kit includes the Renesas Synergy™ S5D9 microcontroller board, at the core of the board.The board includes on-board sensors such as the Renesas Digital Ambient Light Sensor, as well as sensors for microphone, environmental, accelerometer, and magnetometer. These sensors have been labeled on the PCB board for each identification and location. The board has a built in Ethernet PHY chip and Ethernet port and is expandable via the Grove, PMOD, and Arduino headers on the board. While the S5D9 board has an on-board debugger, the JTAG connector provides the option for a developer to connect an external debugger if they so choose.
