In conjunction with signalsrising.org

#Meshtastic Solar Node workshop: build a low-power mesh-communication node based on the NiceRa design — a small form-factor board using an NRF52 (Pro-Micro) microcontroller and an SX1262 radio module.

withfriends.events/event/fHU2qh...
In conjunction with https://signalsrising.org/ In this hands-on workshop, participants will build a low-power mesh-communication nod. These nodes are ideal for deployment in areas with limited infrastructure — for emergency communications, community networks, or off-grid connectivity. Participants should have some familiarity with electronics and microcontrollers (e.g., soldering, flashing firmware) — but we’ll walk through everything step-by-step, so intermediate skill levels are welcome. Ideal for community-tech groups, local disaster-prep teams, NGOs operating in remote areas, or educational groups working on connectivity challenges. Why This Workshop Matters In many underserved or remote regions, traditional communication infrastructure (cell towers, internet) may be unreliable or nonexistent — especially during emergencies (natural disasters, power outages). Mesh networks — where each node can relay messages — offer resilience and flexibility. By building solar-powered nodes, we eliminate dependence on mains power and allow deployment in remote and off-grid locations. The NiceRa design is compact, efficient, and well suited for this purpose (NRF52 + SX1262 radio). The workshop empowers participants not just to build hardware, but to understand how to deploy and manage resilient communication networks — creating real-world impact. Signals Rising provides education and support to the public around radio and other communication technologies. We also provide funding for projects to facilitate growth of the amateur radio community. Signals Rising provides funding and educational resources to underserved individuals and communities to receive radio licensing and equipment. We also sponsor research projects to expand the field of amateur radio communication. All solar nodes built will be distributed to the many communities that have put in requests for assistance in setting up meshtastic systems in their regions.

Not nrf52 as main focus, but there is miceobit v2 version.

But it does not use any external components like in esp32, pico. Most of the exercises with internal components what microbit capable of

This is a fantastic resource! I had a break in my tinkering with MCUs but this got me my groove back 😃 And I finally got to do something with the ESP32 boards, which I've been thinking about for a while. I know there is an RP Pico version, but also an nRF52 would be a good idea, I suppose.

Unfortunately after pouring over the schematic, the only way to insert a voltage before the charge circuit is via the USB-C connector. The 3.3V pin is software switchable output for external devices (LED's), and the VDD pad leads directly to the chip itself (for reprogramming a bricked unit). Ok. 🤷
Module pinout Battery charge circuit from schematic, USB+ is the VBUS power pin(s) on the USB connector The spare pad VDD is VDD_NRF, which directly connects to the nRF52 chip I've marked up the ground and power pins on the rear of the USB-C connector. Outer pins are ground, and the next inner pin is power

With my "shenanigans" I was able to source 10x nRF52 boards for C$32 (paid C$26), 10x IMU boards for C$87 (paid $72), 10x LiPo batteries for C$14, and the recommended PC host dongle (HolyIOT) for C$19.

~C$112 for tracker parts, or C$11 each (i.e. $8 USD). So case aside, yes I beat my ~C$45 goal. 🎉

So as you do, I ordered the parts from AliExpress and moved on with my life (i.e. shipped from China). I planned to build the cheapest 1:1 copy of the SMOL SLIME tracker from AliExpress, so I sourced 10 of each part including the same IMU, though it was cheaper to buy a larger 180 mAh battery vs 120

Well, I was now aware there was a new SlimeVR project based on these nice!nano clone boards: smol slime! They feature a Nordic semiconductor nRF52 family 64MHz ARM microcontroller w/ support for a custom low power 2.4GHz wireless protocol (not WiFi like the ESP variant). Also they can charge a LiPo!

I spent the evening soldering pin headers onto modules. 🤓

I did several ESP32's (S3, C3, C6, H2), WCH RISC-V boards, an nRF52 (nice!nano clone), and I also assembled a single "smol Slime" (AKA a SlimeVR tracker)... though I couldn't find my stash of buttons/switches, so I improvised for testing. 😅
ESP32 modules, some big and some small CH32 modules, a DIY breadboard with a CH32V002 on it, a red nRF52 module, and a black nRF52 with a LiPo battery and white sensor board soldered to it. Blinking lights demo on the nRF52 board with sensor board and LiPo battery attached.

I have stones to throw at all the major vendors, honestly, it's not specifically NXP and STMicro. Even Nordic, who is usually really great, doesn't put warnings in their main datasheet for things like "hey actually this whole functionality doesn't work" (like XIP via QSPI on the nrf52 family)

I was thinking it would be a fun project to replicate this [1] cute tide clock. Fell down a rabbit hole because I knew practically nothing about embedded devices or electronics. A day later, I now know all about MAX7219 controlled LED matrices and the various merits of nrf52/stm32/esp32 SOCs and […]

While not as power efficient as the nRF52, it's still considerably more so than the ESP32, and felt like a great compromise for an all-purpose node with all the feature creep I wanted to let in. And it's tiny! The total size comes out to just barely 60*40mm, about 30% smaller than a credit card.
