KAmodRS485-5V0 is an RS485 communication module based on the MAX485/ST485 that converts TTL signals to RS485; it features a Pmod-compatible connector, a jumper-selectable 120 Ω termination resistor, and operates from 4.75–5.25 V. The board measures 61.2 × 20.3 × 10 mm, includes 2.5 mm mounting holes, and its compact size makes it easy to integrate with development kits and projects.
