About the Receiver PCB

Receiver is an open source ESP32 PCB design by siru409, published on GitHub. It is a 2-layer board measuring 63.6 × 30.9 mm, with 34 components from 17 distinct parts.

Its main chip is the ESP32-C3-WROOM-02, from the ESP32 family. Other key parts include the AP2112K-3.3 and MCP73831-2-OT. By type, the board carries 12 resistors, 10 diodes, 5 capacitors, 3 ICs, 2 connectors and 1 buzzer.

From the project

A near field multi beam ultra wideband fmcw radar detector using a novel near field focussed rotman lens

1. Buttler matrix vs rotman lens -> rotman lense (potentially more array ports within reasonable space) 2. Vivaldi vs Horn Array-> Vivaldi array -> can be implemented in single PCB 3. 2 elliptical dishes vs combined rxtx vs TX dish + 8 fixed RX horns 4. Inductitity values for RX/TX inline buffers 5. 10uF caps 0805 -> price

Receiver: common questions

What microcontroller does the Receiver use?

The Receiver is built around the ESP32-C3-WROOM-02, from the ESP32 family.

How big is the Receiver PCB?

The Receiver measures 63.6 × 30.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Receiver?

34 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the Receiver design files?

From the siru409/Dilf-seeker repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Receiver design in my own project?

The repository has no license, so all rights stay with siru409. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Receiver 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.
