Electronica Azi & Microchip RN2903 LoRa Technology Mote

Win a Microchip RN2903 LoRa® Technology Mote (DM164139) from Electronica Azi and if you don’t win, receive a 15% off voucher, plus free shipping for one of these boards.

The RN2903 LoRa Mote is a LoRaWAN™ Class A end-device based on the RN2903 LoRa modem. The RN2903 is a fully-certified 915 MHz module based on wireless LoRa technology. The RN2903 utilizes a unique spread spectrum modulation within the Sub-GHz band to enable long range, low power, and high network capacity. As a standalone battery-powered node, the Mote provides a convenient platform to quickly demonstrate the long-range capabilities of the modem, as well as to verify inter-operability when connecting to LoRaWAN v1.0 compliant gateways and infrastructure.

The Mote includes light and temperature sensors to generate data, which are transmitted either on a fixed schedule or initiated by a button-press. An LCD display provides feedback on connection status, sensor values and downlink data or acknowledgements. A standard USB interface is provided for connection to a host computer, providing a bridge to the UART interface of the RN2903 modem. As with all Microchip RN family of products, this enables rapid setup and control of the on-board LoRaWAN protocol stack using the high level ASCII command set.

Highlights

  • 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.
