HackerBox 0128 Mesh Deck explores LoRa communication with Meshtastic

For the ~3 other #Arduino folks on the planet trying to solve the same problem I am: if you're desperately trying to find a 3.3V version of a #ProMicro with USB type C, Sparkfun make one with a Raspberry #PiPico RP2350 on board - much faster chip than an Atmel 32U4, runs at 3.3 volts, and no more expensive, plus there's the usual exciting range of faithful and creative clones on AliExpress.

The RP2040 also runs at 3V3 but is tolerant of 5V, for those weird in-between projects. #electronics

My current success rate with #MechanicalKeyboard PCB soldering is currently only 2 out of 5, well 40% is a pass mark - just.

The #RaspberryPiPico #RP2040 ‘Gamma Omega TC36K’ board worked (an easy build, could probably have socketed it). 💚

One success, one failure with #SeeedStudio #Xiao BLE castellated in Forager ‘Acid’ PCB (some fiddly back pads). 🧡

Two failures with #ProMicro #nRF52840 BLE in ‘Gamma Omega Hesse’ board attempting faux-castellation💔

Just as well custom PCBs are fabricated in batches of five - waiting on spare parts to try again - #LearningByDoing or #LearningByFailing ?

If my first wireless Bluetooth #MechanicalKeyboard proves a little battery hungry - and the #ZMK Discord channel suggests the #nRF52840 #ProMicro controller I plan on using can be - there’s an easy fix: Buy a bigger battery! 🪫

In hindsight I was over cautious when I ordered the 300mAh LP602030 battery BEFORE finalising the design, and eked out a few more millimetres for it 😢

Design is here: https://github.com/unspecworks/gamma-omega/tree/main/hesse

Ich hab den Promicro (SX1262) Neustart nach einem Tiefentladen des Akkus mit einer Solarzelle, einem Laderegler und einem kleinen LiPo-Akku im provisorischen Aufbau getestet.

Heute Morgen war es dann so weit - der Akku war leer. Nachdem ich das Solarpanel umgedreht und zur Sonne hin ausgerichtet hatte, startete er von alleine wieder neu.

Bei einem Panel von 10 Watt und einem Akku von 10.000 mAh wird das wahrscheinlich auch im Winter nicht passieren, aber gut zu wissen, dass der Node (Repeater) später “in the wild” auch ohne manuelles Eingreifen wieder neu startet.

Obwohl das Arbeiten (Löten) an diesen FakeTec Nodes für mich eine Herausforderung ist, habe ich noch 5 weitere Nrf52840 Boards und 5 HT-RA62 SX1262 LoRa Module bestellt.

Nach meinen gestrigen Tests (neu Flashen des Bootloaders etc.) bin ich zu dem Entschluss gekommen, dass diese sich gut zum Bau sehr kostengünstiger (Solar) Repeater eigenen würden.
Die Kleinteile (SMD Widerstände, Taster) sind hier ja ohnehin vorhanden, und auch das FakeTec PCB (die Leiterplatte) habe ich dank bereits vorhandenen Gerber-Datei gleich 10 Mal anfertigen lassen (Stück in etwa 0,80 EUR), und so kostet die oben genannte Kombination jeweils nur rund 10 EUR.

Natürlich kommen noch die Kosten für eine Antenne, einem Gehäuse, einem Akku und vielleicht auch einem Solarmodul und anderen Kleinteilen hinzu, aber alles in allem ist dies eine Lösung für den Aufbau eines MeshCore-Netzes hier in Schwerin und Umgebung, in einer durchaus akzeptablen Preiskategorie.

Ooh, my delivery of super mini nrf52840 have arrived. Look at this beauty next to an o/g nice!nano

It can do all the same at 2/3 of the footprint and 1/4 of the price. Plus it has a ceramic Bluetooth antenna so you’d never see BLE dropouts ever again!

They are alive!!!

I soldered all 30 of them, they all work nicely!

These will be some nice pro micro alternatives for mechanical keyboard projects!

https://github.com/plut0nium/0xB2

They have 32 megabit nand flash, the biggest available at the factory.
