Board designed to allow debugging of any onboard
system or full nanosatellite. Board designed compati-
ble with SamSat 2.0 architecture and can be placed
inside nanosatellite.
To power up the nanosatellite it is possible to use
external power supply.
Switching jumpers allow
to select channels to supply.
For
debugging
used
UART interfaces with gal-
vanic isolation between PC
and nanosatellite.
The board connects to
PC using USB interface and
allows
to
program
all
onboard systems.
LED indication simpli-
fies controlling of voltage
channels.
