The Khadas VIM 5 uses the Amlogic A311Y3 SoC, based on the Amlogic A9
SoC family, on a board with the same form factor as the
VIM/VIM2/VIM3/VIM4/VIM1S models. The serial debug console works with this
initial device tree.
It features:
- 8GB LPDDR5
- 64GB eMMC 5.1 storage
- 32MB SPI flash
- 10/100/1000 Base-T Ethernet
- AP6275P Wireless (802.11 a/b/g/n/ac/ax, BT5.1)
- HDMI 2.1 output
- HDMI 2.1 input
- 1x USB 2.0 + 1x USB 3.0 ports
- 1x USB-C with USB 3.0/DP/PD
- 2x LEDs (1x red, 1x white)
- 3x buttons (power, function, reset)
- M2 socket with PCIe, USB, ADC & I2C
- 1x 4 lanes MIPI DSI
- 1x 4 lanes MIPI CSI
- 40pin GPIO Header
- 1x micro SD card slot
