Sipeed MaixSense is a development kit by Sipeed, utilizing their own Sipeed Maix IIA SoM.
On the baseboard, Sipeed logo,
is silkscreened, and on the SoM,
Mainline support is WIP.
You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.
Still being done. To try out the working-in-progress code, retrieve the code at  and use the sipeed_maixsense_defconfig build target.
Still being done. To try out the working-in-progress code, retrieve the code at  and use the sun50i-r329-maixsense.dtb device-tree binary.
Tips, Tricks, Caveats
By default no SPI Flash is soldered, that means just removing SD card makes the SoC to enter FEL.
Adding a serial port
Just plug a cable connected to your PC to the port at the down side (next to the 4-pin connector, which provides another UART, not the debug one). An onboard CH340 USB-UART bridge is available for accessing the debug UART.
