REDE & Microchip WLR089 Xplained Pro Evaluation Kit

Win a Microchip WLR089 Xplained Pro Evaluation Kit (EV23M25A) from REDE and if you don’t win, receive a 20% off voucher, plus free shipping for one of these kits.

Microchip’s WLR089 Xplained Pro is a hardware platform designed to evaluate the WLR089U0 LoRa modules.

The WLR089U0 module is an ultra-low power, regulatory certified LoRa module based on the ATSAMR34J18 LoRa IC. The SAM R34/R35 is a highly integrated family of LoRa technology devices that include an ultra-low-power, a high-performance 32-bit microcontroller (MCU), a LoRa transceiver and a software stack. With their certified reference designs and proven interoperability with major LoRaWAN gateway and network providers, the SAM R34/35 devices significantly reduce time to market for Internet of Things (IoT) end devices.

The WLR089U0 standalone module includes a 32-bit ARM® Cortex®-M0+ processor and offers 256KB of Flash and 40KB of SRAM (8KB battery backed) in a compact 17 x 13.5 mm package. With ultra-low power sleep currents as low as 790nA, the WLR089U0 modules are ideal for battery powered remote sensor applications. The WLR089U0 modules are FCC, IC and RED certified. The WLR089 kit is not only an evaluation platform but also an excellent reference design for developing SAMR34/35 based LoRa end-node applications. 

This kit is supported by the Atmel Studio, an integrated development platform, which provides predefined application examples. The kit also provides easy access to various features of the WLR089U0 module and ATSAMR34J18B device and offers additional peripherals to extend the features of the board and ease the development of custom designs.

  • Using high-precision architectures enables superior DC performance, regardless of operating conditions
  • Low noise and additional EMI filtering on the inputs provide additional protection in electrically noisy environments
  • Small packages, such as leadless DFNs, are ideal for space-constrained designs
  • A wide operating temperature range of –40°C to +125°C provides a robust solution even at extreme temperatures

Microchip Instrumentation Amplifier with mCAL Technology

The MCP6N11 and MCP6V2x Wheatstone Bridge Reference Design demonstrates the performance of Microchip's MCP6N11 instrumentation amplifier (INA) and a traditional three op amp INA using Microchip's MCP6V26 and MCP6V27 auto-zeroed op amps. The input signal comes from an RTD temperature sensor in a Wheatstone bridge. Real world interference is added to the bridge's output, to provide realistic performance comparisons. Data is gathered and displayed on a PC, for ease of use. The USB PIC® microcontroller and included Graphical User Interface (GUI) provides the means to configure the board and collect sample data.
