Setup Information

The default firmware build provides Pulse based Geiger Counter functionality.

Pin Information

The JST header exposes the following pins as marked on the silkscreen

Label	Purpose	Description
GND	GND	Please always have a common ground between your Geiger Counter and the ESPGeiger Log
VCC	5v In	It is possible with some setups to power the ESPGeiger Log from the Geiger Counter
PLS	Pulse Interrupt	Pulse Interrupt Pin

Please also see the additional information in the Outputs section of the documentation.

CAJOE D1 Radiation Setup

It is possible to power the ESPGeiger Log directly from the CAJOE D1 Geiger Counter. The header layout on the board allows for a straight-through connection between the ESPGeiger Log and the CAJOE. See images below for example setups.
