Launched as a crowdfunding campaign on CrowdSupply in Late 2020. Mine arrived in October 2023.
This header claims to match the Raspberry Pi in pinout, but this has yet to be shown. There is zero documentation from the Hackboard team about how to actually utilize any of these pins. At the very least, the power and ground pins match those on the Pi. TxT and RxT are not mapped to ttyS0-3. Similarly, SDA/SCL do not map to any of the i2c interfaces found by linux using the i2c-dev tools.
gpioinfo reports 220 GPIO pins, but testing has not yet begun for mapping those pins to the header.
The header also uses a non-standard 2.0mm pin spacing.
These are likely the same interfaces used by some of the newer LattePanda Alpha/Delta boards. The eDP connector is a 30pin zif. Uses an “A type” cable like this one.
