Durch den konsequenten Einsatz von Ultra-Wideband (Qorvo DW3110 6.5 GHz Ch. 5, $< 0{,}4\,\text{ms}$) und Bluetooth entfällt jegliche Signal- und NF-Audioverdrahtung über den Rahmen. Der Kabelbaum besteht ausschließlich aus robusten 2-Draht-DC-Power-Peitschen (+5V/GND bzw. +12V/GND).

Openmotorbridge pod cartridge: common questions

What microcontroller does the Openmotorbridge pod cartridge use?

The Openmotorbridge pod cartridge is built around the ESP32-S3-WROOM-1U, from the ESP32 family.

How big is the Openmotorbridge pod cartridge PCB?

The Openmotorbridge pod cartridge measures 35 × 25 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Openmotorbridge pod cartridge?

23 components, from 16 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 Openmotorbridge pod cartridge design files?

From the schmidtmt/openmotorbridge 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 Openmotorbridge pod cartridge design in my own project?

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

Can I test firmware for the Openmotorbridge pod cartridge 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.
