#Pickit 3 firmware update software
Microchip provides a comprehensive software package that will do the job, named the “Lora Development Suite”, available for Windows, Linux and MacOS. So I only needed a simple UART2USB adapter, I used one based on CH340G, but you can find many alternatives here. The board hosting the RN2903 already had a pin header with UART connections RX/TX, VCC and GND exposed.

I went for this one and tested the upgrade on a RN2903, already installed in circuit on an uRADMonitor A3 PCB We can use the DFU feature of the RN modules and burn the software via the UART, using the existing bootloader installed in these devices. We are interested in upgrading the firmware running on the PIC18LF microcontroller to the latest software developed by Microchip. Both firmware zip files contain a “combined” HEX that is bigger in size, and an “offset” HEX slightly smaller. Later versions will be published on the product webpage, right under Documentation / Software ( RN2493 / RN2903). You can find them on the Microchip website, here’s v1.0.3 firmware for the RN2483 and this other location holds the v1.0.3 firmware for RN2903. RN2903 Command reference User’s guide Download the new firmware On the RN2903 the PA_BOOST pin is used to get +20dBm, there’s a RF Switch and two band-pass filters. Architectureīoth modules are a combination of a Semtech SX1276 transceiver and a PIC18LF microcontroller:įor the RN2483 there’s a 32MHz crystal, PA_BOOST unused, shared TX and RX network topology, 32KHz crystal. Before that happens, let’s take advantage of what is available now, and see how we can upgrade the firmware on these modules for the latest features and fixes.

Probably things will change to the bright side when Microchip will release the source code for the two. While LoRaWAN technologies have seen an impressive recent boost and Microchip’s modules are among the first on the market, the number of entries in the firmware release notes is rather low, despite huge community interest. I used the RN2483 in my first LoRaWAN project, some time ago. The RN2483 is intended for the 433 MHz and 868 MHz Frequency Bands (Europe), while the RN2903 is for the 915 MHz Frequency Band (US, Taiwan). The PICkit 4 also has a unique programmer-to-go function with the addition of a micro SD card slot to hold project code and the ability to be powered by the target board.The Microchip RN2483 and the RN2903 are Low-Power Long Range LoRa® Technology Transceiver Modules, in the same package and Pin compatible.

Along with a wider target voltage, the PICkit 4 supports advanced interfaces such as 4-wire JTAG and Serial Wire Debug with streaming Data Gateway, while being backward compatible for demo boards, headers and target systems using 2-wire JTAG and ICSP. The MPLAB PICkit 4 programs faster than its predecessor and comes ready to support PIC® and dsPIC® MCU devices. An additional micro SD card slot and the ability to be self-powered from the target means you can take your code with you and program on the go. The connector uses two device I/O pins and the reset line to implement in-circuit debugging and In-Circuit Serial Programming (ICSP). The MPLAB PICkit 4 is connected to the design engineer's computer using a high-speed 2.0 USB interface and can be connected to the target via an 8-pin Single In-Line (SIL) connector. The MPLAB® PICkit™ 4 In-Circuit Debugger/Programmer allows fast and easy debugging and programming of PIC and dsPIC flash microcontrollers, using the powerful graphical user interface of the MPLAB X Integrated Development Environment (IDE), version 4.15.
