MANSFIELD, Texas — Mouser Electronics, Inc. is now stocking the MAXREFDES72 Reference Design from Maxim Integrated. This software configurable interface adapter board allows any board with Pmod™ connectors to be easily plugged into Arduino‑compatible microcontroller platforms. Pmod is an interface standard used to connect peripheral boards to host controller boards.
The Maxim Integrated MAXREFDES72 Reference Design, available from Mouser Electronics, is compatible with Arduino UNO R3, and features a 2×6 Digilent® Pmod-compatible interface. The MAXREFDES72 Pmod‑to‑Arduino interface adapter board consists of the MAX14661 Beyond-the-Rails™ 16:2 multiplexer, two MAX14611 level shifters, and the DS3231M real-time clock (RTC) with an integrated MEMS resonator. Board communication is configured by writing to the MAX14661 multiplexer over the I2C bus. Eight Arduino digital GPIOs are connected to the Pmod interface through level shifters, and each of these 8 GPIOs connect to the multiplexer. The Pmod interface is offered in a convenient, hand-solderable connector that allows developers with an FPGA development board to mix and match professional-grade peripherals into engineering prototypes.
