LoRaWAN Node Shields

My new LoRaWAN node also comes with additional shields to realize the most crazy projects. They are available for order with the any version of the node.

All shields are the same size as the node and are connected with two regular 14 pin headers.
At the moment I developed 3 shields:

• Proto shield
  • Proto area
  • Load switching mosfet circuit controlled by digital pin to power on/off external electronics. With power-on LED.

• RTC shield
  • DS3231 with 3V backup battery.
    The DS3231 also has a programmable interrupt output to wake up the LoRaWAN node every X seconds, minutes, hours, …
  • Small proto area
  • Load switching mosfet circuit controlled by digital pin to power on/off external electronics. With power-on LED.

• RTC & GPS shield
  • DS3231 with battery backup
  • Ultra small GPS module (OriginGPS Nano/Micro Hornet) with onboard, buildin GPS/GLONASS antenna
  • Small proto area
  • Load switching mosfet circuit controlled by digital pin to power on/off external electronics

The RTC/GPS node is only available without GPS module

The new LoRaWAN Node is alive!

 

Last week I found some time to assemble and test my new LoRaWAN Node and here’s the result.

Features of the new board:

• Only 25 mm x 40 mm!
• Low power Atmega1284p microcontroller (Arduino compatible, incl. bootloader & library)
• Standard JST battery connector
• Onboard single cell li-ion / polymer battery charger with charge status LED (charging from USB programmer or solar panel)
• Onboard 3.3V LDO regulator with protection circuit
• Battery voltage measurement
• Breadboard compatible headers
• Reset button
• RGB led
• Extra blue led for RX/TX activity (default color, can be changed on request)
• Full FTDI programming header
• U.FL & SMA antenna connectors
• LoRaWAN:
  • Support for Microchip RN2483 & RN2903 LoRaWAN modules
  • Support for HopeRF RFM9X LoRa modules

The best part of this module is that the LoRaWAN module can be chosen.
I’ve added support for both modules on the same board!

This Node is a perfect starting base for most of my LoRaWAN projects. It’s the same size as the recent Sodaq LoRaONE and a whole lot cheaper! (But there’s no fancy GPS or accelerometer).

New “TvB LoRaWAN Node” in development

After the succes with the first versions of the “TvB Wireless Node’s” I decided to develop a new, upgraded LoRaWAN node.

This new node will support 2 different LoRaWAN modules:

• Microchip RN2483 LoRaWAN module
• HopeRF RFM9X LoRaWAN module

This means the node can be fitted with an RFM95 or an RN2483, whatever fits you best.

Here’s a sneak peek of the new node!

The node is about te same size as the SODAQ LoRaONE and doesn’t have a build in GPS or accelerometer.
When comparing the price tag there’s a huge difference!. Most project’s don’t need fancy extra’s. They only need a compact, powerful and multi purpose LoRaWAN node. So here’s my solution that fits all my use cases.

Changes from the previous version:

• Combined RFM9X and RN2483 design on back-side
• Added voltage protection circuit
• Added battery charger circuit with charging LED for lithium ion battery’s
• Added a small RGB-led
• Changed the programming header to a fully compatible 6-pin FTDI connector.
