Neural Compute Module 6(Neu2) is a 96boards SoM-CB compute module
based on Rockchip RK3588 from Edgeble AI.
General features:
- Rockchip RK3588
- up to 32GB LPDDR4x
- up to 128GB eMMC
- 2x MIPI CSI2 FPC
On module WiFi6/BT5 is available in the following Neu6 variants.
Neural Compute Module 6(Neu6) IO board is an industrial form factor
ready-to-use IO board from Edgeble AI.
IO board offers plenty of peripherals and connectivity options and
this patch enables basic eMMC and UART which is enough to successfully
boot Linux.
Neu6 needs to mount on top of this IO board in order to create a
complete Edgeble Neural Compute Module 6(Neu6) IO platform.
