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.

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.






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.

The cost for the PCB is £4 + £1.50 postage Worldwide, I will include the 2.0mm pin headers needed for the RFM98.






RFM98 Shield BoardShield V2

This is a board for the Hope RFM98.The board can be used as bench or portable receiver and powered either by a 3.3V Arduino Pro Mini or as a shield plugged into a 3.3V Arduino UNO base or 3.3V Ardunio ATMEGA2560 base. The board is also ideal for building a portable receiver when used with an Arduino Pro Mini. There are connections for a GPS, switches, Digole style serial display and a Bluetooth adapter.

The HAB receiver software allows for remote control and configuration of the in-flight tracker. There are details, assembly instructions and code to use this board as a bench receiver for HAB tracking here,

Bench Receiver

The board can also be used to build a portable LoRa receive, details assembly instructions and code will be found here;

Portable LoRa Receiver

When plugged into an ATMEGA2560 base, the GPS cannot be used as the softserial is not available on the pins used on the board. I am waiting on delivery of a board that will correct this.

The cost for the PCB is £3 + £1.50 postage Worldwide, I will include the 2.0mm pin headers needed to mount the RFM98.






Display BackpackBackPack1

The backpack PCB is designed to turn the Nokia 5110 graphic displays into a serial text displays compatible with the Digole style serial protocol. The display needs only one I\O pin avaialble to drive it. The supplied board splits into two seperate backpacks. Details, assembly instructions, reports and diagrams will be found in the ‘Display Backpack’ Folder here;

Display Backpack

The cost for the PCB is £3 + £1.50 postage Worldwide.






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.

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.

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 PCBGPS Breakout PCB x 2

Order this and you will get a PCB that will allow you to build two GPS breakout boards, these are often used in PICO balloon trackers. You can fit either a ceramic antenna or a 1/4 wave or 3/4 wave wire antenna with radials for improved GPS reception. Board details and schematics are in the GPS Breakout folder on the dropbox.

The cost for the PCB is £2.50 + £1.50 postage Worldwide.




HAB2 High Altitude Balloon Tracker PCBThis board allows for a minimal part count high altitude balloon traker to be built. If your powering it from 2 x AAA batteries the only parts you need are a 3.3V Arduino Pro Mini, DRF1278F Lora device, a UBLOX Max8Q GPS and some wire.

The build instructions will be found in the HAB2 repository here.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) which will build two trackers, is £3 + £1.50 postage Worldwide, I will include the 0.05″ pin headers needed to mount the DRF1278F.
