About the A3P250 Dev Board

A3P250 Dev Board is an open source PCB design by oresat, published on GitHub under the CERN-OHL-S-2.0 license. It is a 4-layer board measuring 46 × 46 mm, with 49 components from 24 distinct parts.

Other key parts include the A3P250, LTC3561A and LT1962-3.3. By type, the board carries 29 capacitors, 8 resistors, 4 connectors, 3 ICs, 2 diodes and 2 inductors.

It belongs with the rf & radio and dev boards & breakouts designs in this gallery.

From the project

Hardware for OreSat's SDR GPS receive and other SDR GPS projects

This is the repo for our OreSat GPS Card. For software, see the oresat-gps-software repo.

A SkyTraq Orion-B16 GNSS module, a GNSS receiver module meant for university CubeSat use. An Analog Devices MAX2771 SDR GNSS receiver IC that is read by the Octavo OSD335x-SM processor's PRU and then parsed using the GNSS-SDR project software.

TRL 6-7 ish. Flown, but not yet demonstrated to work in space.
