Overview
ThunderBuddy is an open-source printed circuit board by gamblor21, from the gamblor21/ThunderBuddy repository on GitHub. It is a 2-layer board of 26.7 × 28.4 mm with 17 parts on 14 nets, routed with 116 tracks and 15 vias.
It is built around the MA5532-AEB. Its parts include 5 capacitors, 5 resistors, 1 IC, 1 connector and 1 inductor. It belongs with the sensors and measurement boards of this library.
Main components
1README
README.mdThunderBuddy
This small circuitboard uses an AS3935 chip to detect lightning at distances up to 40km away. By default it supports SPI but can be configured for I2C as well.
The board measures around 2cm a side with a small lightning shaped antenna area on top.
The board can be driven in CircuitPython with the AS3935 driver.
For an example project using the board please see my Lightning Detector project.

Questions
How big is the ThunderBuddy PCB?
It measures 26.7 × 28.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ThunderBuddy use?
17 parts, built around the MA5532-AEB. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ThunderBuddy KiCad files?
From the gamblor21/ThunderBuddy repository on GitHub, at the commit this page was made from: the board is ThunderBuddy.kicad_pcb and its schematic ThunderBuddy.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ThunderBuddy design in my own project?
Its repository states no licence, so its author keeps all rights: ask gamblor21 before reusing the design.
