Connector J1 accepts 5V input voltage and is used to supply power to the Skywire 4V Power Supply. The acceptable input Voltage range for J1 is 4.8-5.2V. Do not exceed 5.5V. The Skywire Cellular Modem will regularly consume high amounts of current (~750 mA) from the adapters power supply. It is recommended to have 1A of available​ ​source​ ​current​ ​available​ ​for​ ​the​ ​adapter​ ​board.

Operating​ ​Modes 3.1 RL78/G13​ ​Demonstration​ ​Kit​ ​PMOD​ ​Adapter 3.1.1 About The PMOD interface on the Skywire RL78-Kurumi Adapter adheres to the Digilent PMOD specifications for Type 2A (Expanded SPI) PMOD Interface with a​ ​standard​ ​twelve-pin​ ​connector. The PMOD interface connects to the Renesas Demonstration Kit for the RL78/G13 (YRDKRL78G13) through the PMOD2 connector. The adapter’s onboard SPI to UART converter provides protocol translation allowing for the demonstrations kits Type 2A (Expanded SPI) PMOD Interface to communicate with​ ​the​ ​Skywire​ ​module. 3.1.2 Block​ ​Diagram PN​ ​30018​ ​rev​ ​2 ​©​ ​NimbeLink​ ​Corp.​ ​2017.​ ​All​ ​rights​ ​reserved. 7 3.1.3 Switch​ ​Configuration SW1 is used to control the configuration mode of the adapter.
