Rt hw v1: common questions
What microcontroller does the Rt hw v1 use?
The Rt hw v1 is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the Rt hw v1 PCB?
The Rt hw v1 measures 113.4 × 65.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Rt hw v1?
81 components, from 45 distinct parts. The full bill of materials is listed on this page.
Where can I download the Rt hw v1 design files?
From the ahsanu123/crumbs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Rt hw v1 design in my own project?
Yes, under the terms of its MIT license, which ahsanu123 chose for the repository.
Can I test firmware for the Rt hw v1 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.
