- square plastic case
- Amlogic S905W (ARM Cortex-A53) quad-core up to 1.5GHz
- no video out
- 1GB LPDDR4
- 8/16GB eMMC flash
- 2 x USB 2.0
- 1 x 10/100Mbps ethernet
- WiFi / Bluetooth RTL8822CS IEEE 802.11a/b/g/n/ac, Bluetooth 5.0.
- TI CC2538 + CC2592 Zigbee Wireless Module with up to 20dBm output power and Zigbee 3.0 support.
- MicroSD 2.x/3.x/4.x DS/HS cards.
- 1 x gpio LED
- ADC user Button
- DC source 5V microUSB
