The Indiedroid Nova is an SBC from a sub-brand of Ameridroid that includes the following hardware:
- A 40-pin GPIO header - 2 USB-A 3.0 ports - 2 USB-A 2.0 ports - A USB-C 2.0 OTG port (used for USB power delivery) - A USB-C 3.0 port that can do display port output. - A Micro HDMI 2.1 port. - A 1GB ethernet port. - An RT8821CS based WiFi/Bluetooth module. - A user replaceable eMMC module. - An SDMMC card slot. - A MIPI DSI connector. - A MIPI CSI connector. - A 3.5mm TRRS audio jack with microphone input. - An 2 pin socket for an RTC battery. - A 4 pin socket for a debug port. - A power button (connected to PMIC), a reset button (connected to SoC reset), a boot button, and a recovery button (both connected to the ADC). - 4GB, 8GB, or 16GB of system RAM.
This initial devicetree includes support for the WiFi, bluetooth, analog audio out/in, SDMMC, eMMC, RTC, UART debugging, and has the regulator values from the schematics. ADC, graphics output, GPU, USB, and wired ethernet are still pending additional upstream changes.
