LoRa click carries Microchip’s RN2483 fully certified LoRa Sub-GHz, 433/868 MHz European R&TTE Directive Assessed Radio Modem. Two antenna connectors allow you to choose which of the two frequency bands will be employed.

LoRa 2 click carries Microchip’s RN2903 915 MHz Radio Modem compliant with regulations for use in the United States, Canada, Australia and New Zealand.

Both modules has a specified range of >15km in rural and suburban settings, and >5km coverage in urban areas. A LoRaWAN™ Class A protocol stack is embedded (bidirectional end devices), as well as an ASCII command interface accessible through UART. The high receiver sensitivity can go down to -148 dBm. They communicates with the target board MCU through the mikroBUS UART interface (CTS, TXD, RXD), with the addition of a Reset pin (RST). The board is designed to use either a 3.3V or a 5V power supply.

LED Driver 2 Click

LED driver 2 click carries the MCP1643 - LED constant current regulator, made by Microchip. It is a compact, high-efficiency, fixed frequency, synchronous step-up converter, optimized to drive one LED with the constant current. It can be powered by a two-cell alkaline/NiMH/NiCd battery (2.4V), or via the mikroBUS™ power supply pins.
