BananaPi M2S ships in Amlogic S922X and A311D variants with the
following common specifications:

- 16GB eMMC
- HDMI 2.1a video
- 2x 10/100/1000 Base-T Ethernet (1x RTL8211F, 1x RTL811H)
- 2x USB 2.0 ports
- 2x Status LED's (green/blue)
- 1x Power/Reset button
- 1x micro SD card slot
- 40-pin GPIO header
- PWM fan header
- UART header

The S992X variant has:
- 2GB LPDDR4 RAM

The A311D variant has:

- 4GB LPDDR4 RAM
- NPU (5.0 TOPS)
- MIPI DSI header
- MIPI CSI header

An optional RTL8822CS SDIO WiFi/BT mezzanine is available for
both board variants.
