100 Gadget Ideas - Napkin to Billboard

This directory contains firmware for the returnfrom.space showcase project. Hardware kits can be obtained from returnfrom.space.

Edit the firmware using Thonny and upload it to the boards.

- Console — RP2040 based. Configured as a USB keyboard with 16 tactile switches. Provides UART output at 115200 bps. - SEB — ESP32-S2 based. Includes drivers for an SSD1306 display, DAC and ADC sampled at 8 kHz, with UART input. - Delta — ESP32-S2 based. Similar to SEB with its own pin mappings and peripherals.

Spacescape: common questions

What microcontroller does the Spacescape use?

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

How big is the Spacescape PCB?

The Spacescape measures 205 × 140 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Spacescape?

327 components, from 47 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 Spacescape design files?

From the Napkin-to-Billboard/100GI repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Spacescape design in my own project?

Yes, under the terms of its MIT license, which Napkin-to-Billboard chose for the repository.

Can I test firmware for the Spacescape 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.
