After searching for a budget friendly TTL to RS422/485 converter board I was astonished to only find products that were $45 plus and bulky for such a simple and common use case.

This lead me to design this TTL to RS422/485 converter board for interfacing microcontrollers to industrial sensors and controllers.

The design features: - Full duplex communication with the Texas Instruments SN65HVD33 transceiver, ensuring seamless full-duplex communication. - Two dedicated ground reference pins for RS422/485 output. This not only enhances signal quality but also reduces the risk of noise interference, making your data communication smoother. - 120 Ohm termination resistors for improved signal integrity - ESD protection on all signal pins - Compact 40mm x 25mm design - Professional and easy to use Molex 6-pin Picoblade connectors. These are extremely common with pre-crimped cables readily available.

Package Contents: 1x TTL to RS422 Transceiver Board 2x Pre-crimped 6-pin Picoblade Connector cables with 15cm length
