The Remington #2 was the first typewriter with "macros" - it typed lowercase or uppercase based on whether the user was holding the Shift key. This modern, battery powered keyboard is much smaller and more portable than that original typewriter, but has lost a key. Since this layout is missing the right Shift, it's a version before the Remington #2 - the Remington #1.1

Reminton-Num-1.1: common questions
What microcontroller does the Reminton-Num-1.1 use?
The Reminton-Num-1.1 is built around the XIAO-RP2040-DIP, from the RP2040/RP2350 family.
How big is the Reminton-Num-1.1 PCB?
The Reminton-Num-1.1 measures 71 × 88 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Reminton-Num-1.1?
23 components, from 4 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 Reminton-Num-1.1 design files?
From the O-Lidenbrock/Reminton-Num-1.1 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 Reminton-Num-1.1 design in my own project?
The repository has no license, so all rights stay with O-Lidenbrock. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Reminton-Num-1.1 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.
