About the Input PCB

Input is an open source ESP32 PCB design by earlynerd, published on GitHub. It is a 4-layer board measuring 21 × 55.9 mm, with 69 components from 40 distinct parts.

Its main chip is the ESP32-C6-MINI-1, from the ESP32 family. Other key parts include the DRV2625YFFR, BQ25186DLHR, TPS63802DLAR, TPD2EUSB30DRTR and M2003FC1AE. By type, the board carries 29 resistors, 20 capacitors, 8 ICs, 4 connectors, 3 switches and 1 module.

From the project

See ../../../docs/main-board-placement.md for constraints and distances. main.kicad_pcb is the applied 70-part checkpoint; placement.png/svg show native pads and courtyard bounds. The active sources are ../../main/. Current acceptance reports are ../project-split/.

input.kicadpcb is the user placement with the new Tag-Connect footprint synchronized before optimization. previous.xml and active-latest capture intermediate redraw checks; they are historical. metrics.json is an earlier candidate measurement and is superseded by critical-distances.json and the final native reports.…

The KiCad project lives in the earlynerd/ELRS-haptics repository on GitHub; these links point at the commit this page was built from.

Input: common questions

What microcontroller does the Input use?

The Input is built around the ESP32-C6-MINI-1, from the ESP32 family.

How big is the Input PCB?

The Input measures 21 × 55.9 mm, has 4 copper layers and is 0.8 mm thick.

How many components are on the Input?

69 components, from 40 distinct parts. The full bill of materials is listed on this page.

Where can I download the Input design files?

From the earlynerd/ELRS-haptics repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Input design in my own project?

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

Can I test firmware for the Input without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
