About the BaseplateRev1 PCB

BaseplateRev1 is an open source RP2040/RP2350 PCB design by Kmshanley, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 58 × 64 mm, with 30 components from 14 distinct parts.

Its main chip is the antenna, from the RP2040/RP2350 family. Other key parts include the TMP117MAIDRVR and OPT4048DTSR. By type, the board carries 8 connectors, 4 ICs, 4 resistors, 2 transistors, 2 test points and 2 capacitors.

It belongs with the sensors designs in this gallery, and the repository also holds 1 earlier revision of it.

From the project

The pocket cube standard requires satellites to be 5x5x5cm and under 250 grams. Upon completion of this Wentworth PicoSat it will become one of the smallest satellites capable of high resolution imagery from LEO.

BaseplateRev1: common questions

What microcontroller does the BaseplateRev1 use?

The BaseplateRev1 is built around the antenna, from the RP2040/RP2350 family.

How big is the BaseplateRev1 PCB?

The BaseplateRev1 measures 58 × 64 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the BaseplateRev1?

30 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the BaseplateRev1 design files?

From the Kmshanley/PicoSat-Initiative repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the BaseplateRev1 design in my own project?

Yes, under the terms of its GPL-3.0 license, which Kmshanley chose for the repository.

Can I test firmware for the BaseplateRev1 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
