CTA28 App. boards

CTA88 chip based 2 channel application boards

The CTA88 chip is a simple encoder/decoder for use with ISM band telemetry modules. It permits a simple, one way wireless link to be established, for simple remote control applications, with a minimum of effort and no customer software input.
These tx and rx application boards are designed to allow easy evaluation of the CTA88 device in elementary jobs. They provide simple 2 channel implementations, using either LMT/LMR or BiM footprint radio modules.
