DRF1278F LoRa Modules with HAB Tracker or Lost Model Locator BoardsLoRaTracker_Locator1_Blank_PCB

Order this and you will get two Dorji DRF1278F LoRa modules and a PCB.This is the updated board – LoRaTracker_Locator2. The board can take a I2C FRAM which will be used in a future revision of the Lost Model Locator software, the FRAM is not needed for the current software. Details and assembly instructions will be found in the  Locator2  folder here;

LoRaTracker_Locator2

The tracker PCB can be used as a HAB receiver (bench or portable) with a serial terminal as the output and an audio link uplink into FLDIGI. The supplied PCB splits into two tracker boards, either can act as transmitter or receiver.

Included with the tracker PCBs is a Version 4 display backpack board, which allows displays such as ILI9341 and Nokia 5110 to be connected via an I2C connection. See the display repository here for code and details.

The cost for the two LoRa modules and PCB is £15 + £1.50 postage Worldwide, the 0.05″ pin headers needed for the DRF1278F are included.






RFM98 HAB Tracker and Lost Model Locator BoardsRFM98

This is a board for the HOPE RFM98 LoRa device. The board can be used as a High Altitude Balloon (HAB) tracker and receiver or a Lost Model Locator transmitter and receiver.There is now a location to fit a 250mA 1206 size Polyfuse on the rear of the PCB, you can bridge the pads with wire if you choose not to fit it.

Details, assembly instructions and code for the HAB tracker Build will be found in the ‘LoRa HAB Tracker’ folder here;

LoRa HAB Tracker

The assembly of this minamalist design was posted as a blog post here;

http://www.loratracker.uk/?p=30

The blog post was for a tracker based on the DRF1278F device, but assembly with the RFM98 is very similar.

Details, assembly instructions and code for the Lost Model Locator build will be found in the ‘LoRa Lost Model Locator’ folder here;

Lost Model Locator

The supplied PCB splits into two tracker boards, nominally a transmitter and a receiver, although they will each do either.

Included with the tracker PCBs is a Version 4 display backpack board, which allows displays such as ILI9341 and Nokia 5110 to be connected via an I2C connection. See the display repository here for code and details.

The cost for the PCB is £4 + £1.50 postage Worldwide, the 2.0mm pin headers needed to mount the RFM98 are included..






DRF1278F Lost Model Locator Kit

I have collected together the small parts required to build the DRF1278F Lost Model Tracker into a Kit.

The Mini-Kit includes two DRF1278F modules, the PCB and the small parts to build two trackers or a tracker and a receiver.

The contents of the kit are listed in the file “Locator2 Kit Contents.XLS” that can be found in the ‘Parts’ folder here;

Lost Model Locator2

The kit does not contain, Arduino Pro Mini, GPS, Serial Programming adapter, wire or solder.

Included with the tracker PCBs is a Version 4 display backpack board, which allows displays such as ILI9341 and Nokia 5110 to be connected via an I2C connection. See the display repository here for code and details.

The cost of the Kit is £28.50 for UK Delivery, rest the World delivery £31 Please select the appropriate option below.

DRF1278F Modules and PCB for LoRa RelayRelay PCB

Order this and you will get two Dorji DRF1278F LoRa modules and a PCB for building two LoRa Relays .

Board details and code for the LoRa Relay will be found in the ‘LoRa Relay’ folder here;

LoRa Relay

Construction and use of the relay was the subject of a Blog post starting  here;

LoRa Relay, Building and using

The supplied PCB splits into two relay boards, the board can also be used as a basic but very small LoRa tracker transmitter or receiver.

Included with the tracker PCBs is a Version 4 display backpack board, which allows displays such as ILI9341 and Nokia 5110 to be connected via an I2C connection. See the display repository here for code and details.

The cost for the two LoRa modules and PCB is £15 + £1.50 postage Worldwide, I will include the 0.05″ pin headers needed for the DRF1278F.






UBLOX MAX 8MQ  GPS Breakout BoardGPS Breakout 200917

This is a revision of the previous GPS Breakout PCB. There is the option of fitting a simple wire antenna which I have found performs better than the often used ceramic stick antenna. Since the edge connector has the I2C connections as well as serial I have added the pads to allow an I2C TC74 temperature sensor to be fitted. There is also a 4 pin I2C header to which a BMP280 or BME280 sensor can be fitted. For further details click here.

Order this and you will get 3 GPS breakout PCBs.

The cost for the 3 of the breakout PCBs is £2 + £1.50 postage Worldwide.






HAB2 LoRa High Altitude Balloon Tracker Board

This board allows for a minimal part count high altitude balloon traker to be built. If your powering it from 2 x AAA Lithium batteries the only other parts you need are a 3.3V Arduino Pro Mini, DRF1278F Lora device, UBLOX Max8Q GPS and some wire. The build instructions and software will be found in the HAB2 repository here.

The HAB2 software will send its location payloads in LoRa and FSK RTTY, there is an option for FSK RTTY only mode. In addition the HAB2 software allows for remote control of the tracker in flight. Whilst primarily designed for use in Pico balloons, the board can be used as a tracker for the larger 30,000M + balloons. You can attach an external tracker antenna by fitting an SMA edge socket and the 2 tracker PCBs also come with one GPS breakout PCB so you can connect the GPS by a short cable and have the wire antenna on the outside of the payload.  

LoRaTracker_HAB1

The tracker board can be used as a receiver too, see the Receiver1 repository on the above link. Picture on the right shows the assembled tracker.

The cost for the bare PCB (no other components) and one GPS breakout PCB which will build two trackers, is £3 + £1.50 postage Worldwide, I will include the 0.05″ pin headers needed to mount the DRF1278F.






LCD Receiver Mini Kit

This is a mini kit to build the LCD Receiver, it is described in the LCD Receiver Build document here;

LCD Receiver BuildLCD Receiver

The receiver has been designed primarily as a LoRaTracker receiver, easy to build and with minimal components. There are 2 Mikrobus bus sockets intended for a LoRa device and a GPS, but you can fit other Mikrobus ‘Click’ boards as well. It can be a transmitter as well.

A 20 character x 4 line LCD fits on top of the main PCB and forms a compact unit with a large display that is readable in direct sunlight. There are different versions of the software, one for a portable receiver for field use and searching, one a serial terminal based receivers and remote controller for the high altitude balloon tracker software and a third version will provide data logging to an on board Micro SD card. There are full build instructions provided.

The Mini kit includes all the parts that can take you a while to collect together. You will need to source some components yourself, the mini kit does not include an Arduino Pro Mini 3.3V, LCD Display, GPS, UHF antenna or battery. You will save substantial amounts of money if you source these yourself, its just not possible to compete with eBay prices for some components.

A full list of the components in the mini kit is here;

Mini Kit parts list

The price of the mini kit is £22 including World Wide postage.
