All of the DLP-RFS1231s electronics (including an antenna) reside on a single PCB, and all operational power is derived from a single supply voltage. The transceiver design is made up of a Renesas RL78 low-power microcontroller (R5F100EEANA), a Semtech SX1231 low-power, integrated UHF transceiver and an antenna switch for selecting between the on-board antenna and an optional external antenna. The hardware is designed for maximum range and optimum battery life.

The serial number can be read via the microcontroller and used to identify the transceiver in the transmitted packets. 2.2 HOST CONNECTION UART TX RXD1 RXD1 UART TX UART RX TXD1 TXD1 UART RX HOST A RFS1231 RFS1231 HOST B 2.3 QUICK-START GUIDE This Quick-Start Guide is designed to work with our DLP-RFS1231 transceiver and DLP-RFS-BATT battery board Development Kit. (The part number for this kit is DLP-RFS-DK.) The kit contains two DLP-RFS1231 transceivers, two DLP-RFS-BATT battery boards and a Tag-Connect adapter for use with the Renesas E1 debugger (purchased separately).
