About the TX 50MHz 1W PCB

TX 50MHz 1W is an open source ESP32 PCB design by ne9n, published on GitHub. It is a 2-layer board measuring 232.3 × 186.9 mm, with 51 components from 38 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N16R8, from the ESP32 family. Other key parts include the Si5351A-B-GT, BGS12SN6E6327XTSA1 (T/R SW), SPF5043Z (LNA), LT5560 (Mixer) and ADS1115IDGSR (0x48). By type, the board carries 17 capacitors, 11 connectors, 10 ICs, 6 inductors, 4 resistors and 1 transistor.

It belongs with the rf & radio and power & battery designs in this gallery.

From the project

This project focuses on designing and building a modern 50MHz (6-meter) radio control system using the amateur radio bands. It features a high-power 1W transmitter and a high-sensitivity receiver, integrated into a vintage Kraft 7 transmitter case with a modern digital encoder.

TX 50MHz 1W: common questions

What microcontroller does the TX 50MHz 1W use?

The TX 50MHz 1W is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.

How big is the TX 50MHz 1W PCB?

The TX 50MHz 1W measures 232.3 × 186.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TX 50MHz 1W?

51 components, from 38 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 TX 50MHz 1W design files?

From the ne9n/RC_6m 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 TX 50MHz 1W design in my own project?

The repository has no license, so all rights stay with ne9n. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the TX 50MHz 1W 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.
