About the Sprite PCB

Sprite is an open source Microchip SAM PCB design by RoboticExplorationLab, published on GitHub. It is a board measuring 47.2 × 35 mm, with 77 components from 30 distinct parts.

Its main chip is the ATSAMD51G_TQFN48, from the Microchip SAM family. Other key parts include the BAT-HLD-001, CC1101RGPR, LSM9DS1TR, TPS82740ASIP and OVM9724. By type, the board carries 27 connectors, 24 capacitors, 8 ICs, 6 resistors, 5 switches and 2 antennas.

It belongs with the sensors and rf & radio designs in this gallery.

KickSat Sprite (2019) running Circuitpython

hardware: KiCad PCB files and bill of materials. Assembling a sprite? Check out https://roboticexplorationlab.github.io/sprite/ for an interactive BOM!

firmware: pre-built circuitpython bootloader.bin and firmware.uf2 (and the files to build it yourself)

software: circuitpython scripts and libraries working on the sprite

Put all the files located in /software/ on to the sprite and start the serial console (as described above). After pressing Ctrl+C to halt the sprite, press any key to enter the REPL, then type

Sprite: common questions

What microcontroller does the Sprite use?

The Sprite is built around the ATSAMD51G_TQFN48, from the Microchip SAM family.

How big is the Sprite PCB?

The Sprite measures 47.2 × 35 mm and is 0.8 mm thick.

How many components are on the Sprite?

77 components, from 30 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Sprite design files?

From the RoboticExplorationLab/sprite repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Sprite design in my own project?

The repository has no license, so all rights stay with RoboticExplorationLab. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Sprite without the hardware?

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