Neural Compute Module 2(Neu2) is a 96boards SoM-CB compute module based on Rockchip RV1126 from Edgeble AI.
General features: - Rockchip RV1126 - 2/4GB LPDDR4 - 8/16/32GB eMMC - 2x MIPI CSI2 FPC connector - Fn-link 8223A-SR WiFi/BT
Industrial grade (-40 °C to +85 °C) version of the same class of module called Neu2k powered with Rockchip RV1126K.
Neu2 needs to mount on top of Edgeble IO boards for creating complete platform solutions.
Add support for it.
