Raspberry Pi sense hat board


Board contains an 8x8 array of tri color leds.

Also the following sensors and utility:

ST Micro inav unit
   contains orientation and compas sensor

ST micro pressure / temp / humidity sensor

Joystick

When installed on a raspberry pi 4, has to have a config setting changed to force on an HDMI port.  Don't know if it's because there are two of these on the board, or if it's because of a gpio / programming conflict, but when run headless, the board won't boot w/o that change.

Solution was to edit the /boot/config.txt.
Remove the "#" in front of the line "hdmi_force_hotplug=1" and now the Raspberry Pi is booting attached with the SenseHAT.
