Heartbeat module
Resolve both snapback and PODE with a combination of capacitors and resistors.

Brand new analog sticks usually have snapback, and as potentiometers wear, they tend to develop PODE. A heartbeat module is a set of adjustable capacitors and resistors designed to mitigate both of these unwanted effects.
How it works
Just like a standard snapback module, capacitors are used to smooth out unwanted inputs caused by the analog stick overshooting the return to center due to the tension of the stickbox spring. A heartbeat module adds resistors that selectively drain built-up discharge within the potentiometer, removing the variance in current throughput caused by PODE.
Parts
Heartbeat modules are available from several sellers. Note that availability may vary.
- Rienne heartbeat module — the original module by Rienne, the pioneer of the heartbeat module
- RockerGaming heartbeat module — the same module sold by Rocker, a collaborator on the original project
- Heartbeat daughter module by Kadano (for use with Kadano’s snapback module)
- Open Heartbeat Module — an open-source module design you can order from JLCPCB, by Savestate
Process
Installing a heartbeat module is basically identical to installing a snapback module, and involves soldering the module to the motherboard. Make sure to follow the instructions included with the module.
