HEXAGON is an open hardwrae development board built around 480 MHz Renesas MCU (Arm® Cortex®-M85 core with HeliumTM).
The board was designed as there was nothing similar meeting our demands at the moment.
Along with Cortex®-M85 in BGA package the hardware design also includes:
✔ 8 MB SDRAM
✔ 32 MB QSPI
✔ Stereo Audio Codec (for voice recognition applications development) with 3.5mm jack connector for headphones and microphone
✔ USB interface with USB-C connector (MCU USB and/or power)
✔ Ethernet interface with RJ45
✔ CAN interface with D-SUB connector
✔ RS485 interface with D-SUB connector
✔ Flexible power supply (from 5 to 30VDC) with barrel jack connector and an option to power the board from USB
✔ Reset button and power supply LEDs
✔ 2 user buttons and 3 user LEDs
The board design contains 8 layers including 4 signal layers, 3 ground planes and 1 power plane.
Some components (MCU, QSPI) are in BGA packages and may be hard to assembly manually.
