Hardware

The WX series

WX stands for Wrewtopia Labs eXperimental. Each board is designed in KiCad, fabricated in small batches and brought up by hand. The letter after the number is the board revision.

The WX-1E Bit Blaster: a black PCB with a CC1101 chip, a 2×6 header on the left, and two right-angle SMA connectors labeled 315/433 and 868/915.
WX-1E Coming soon

Bit Blaster

Dual-band CC1101 sub-GHz radio for the LilyGO T-LoRa Pager.
KiCad render of the WX-2E SD-F main board: a tall black PCB with an ESP32-S3 module footprint at the top, buttons in the middle, and a rotary encoder near the bottom.
WX-2E In development

SD-F

Handheld surveillance detection and direction finding.
The WX-3A El Duderino: a blue PCB with an ESP32-S3 module, a microSD slot, two tactile buttons and a USB-C cable plugged in.
WX-3A Prototype

El Duderino

A big red button that plays a random sound.
The WX-4A Spectra held in hand: a long blue PCB with an ESP32-C5 module, an Ai-Thinker Ra-01SH LoRa module, breakout holes along both edges and a USB-C cable plugged in.
WX-4A Coming soon

Spectra

ESP32-C5 LoRa dev board with dual-band Wi-Fi 6.

How the lab works

Small shop, whole stack

Schematic first

Every board starts from a schematic with each pin checked against the datasheet, then goes through layout, fab and bench bring-up.

Firmware to desktop

The same lab writes the ESP32 firmware for the boards and the Rust desktop and server software for Veilamp, and ships signed packages for it.

Built in the open

Wins, failed spins and fixes are written up on the build log, so you can see how each design got to where it is.
