Microchip Technology WLR089 Xplained Pro Evaluation Kit (EV23M25A)
Microchip Technology WLR089 Xplained Pro Evaluation Kit (EV23M25A) is a hardware platform used to demonstrate the features of the low power LoRa® Sub-GHz WLR089U0 Module. The WLR089U0 Module, based on the ATSAMR34J1 32-bit Arm® Cortex®-M0+ Processor, provides 863MHz to 928MHz dual-band coverage. With ultra-low power sleep currents as low as 790nA, the Microchip WLR089U0 module is ideal for battery-powered remote sensor applications.
The Microchip Technology WLR089 Xplained Pro Evaluation Kit features a pre-installed WLR089U0 Module, along with an onboard debugger, extension headers for signal breakout or expansion boards, 10-pin Cortex programming header, and an onboard power management system with current monitoring. The Evaluation Kit functions as a reference design for developing SAMR34/35-based LoRa end-node applications.
