(All technical information about the REDBOX MINI 5 device, including the ability to build the Linux ARMBIAN distribution.)
Important: The data in this repository is experimental and may contain errors. This repository was developed primarily for devices with V1 and V2 specifications. Devices with less RAM and permanent memory, or different processors, are not currently supported.
Important: Users are solely responsible for making decisions about using this data and for collecting images to run third-party software.
CPU: Allwinner H5 (AArch64, x4, 0.2Ghz-0.912Ghz (1.01 GHz works too))
MEM: 1GB (DDR3, 336.00 GHz - 672.00 GHz (1344.01 GHz works too))
Eth: Internal (100mbit)
WI-FI: XR819 (was not considered)
USB: x2 2.0, (works, presumably the board has contacts for additional USB.)
EMMC: Q2J55L (7.09 GiB) (works but not guaranteed)
GPIO: LED_PWR (1c20800, 15-PA15), LED_STATUS (1f02c00, 362-PL10), IR (1f02c00, 363-PL11), KEY_RESET (1f02c00, 355-PL3) (On this board you can get absolutely any gpio that is available on allwinner h5 (I’m just giving a list of those pins that you can get without much effort).)

Just like on V1, the contacts are marked on the board.
These devices use a constant 1.1V voltage, which cannot be adjusted. This means that higher processor frequencies like 1.2/1.5 GHz are not achievable.
WI-FI support is not currently available due to difficulties in obtaining compatible driver code. The chip itself is not very efficient for wireless communication, so wired connections (Ethernet or USB Wi-Fi) are preferred.
I2C support is not available, as all I2C buses in the device tree are currently disabled.
TODO? In theory, you can potentially use pins PL0 and PL1, which are intended for the WI-FI chip, for I2C communication. However, this would require additional configuration and testing.
