I decided to fix the broken trace I so naively destroyed while breaking the power LED out with a screwdriver. The image from @tripy really helped to figure out which trace I actually broke. It helped a lot to desolder the voltage regulator as well, leaving me with pads I can solder to. I left the regulator out after the repair since I am running the thing from 5V USB.
With the regulator out of the way the correct pad was easily identified.
Maybe someone else finds this useful, definitly saved my kitchen lighting project today
No, I didn't seriously consider it. I have a minimal programming circuit with ZIF-sockets to program DIPs, but those are easily removed from a circuit (assuming they are put into sockets and not soldered) in case they need to be reproprammed . Doing this with a TQFP seems like a one-way road, so I think a way for in-circuit programming should be provided regardless.
I mean, I didn't have to reprogram my first revision nodes so far, but I might want to add signing support later on or upgrade to MySensors 2.4 or 3.0 for some reason, so it should definitely be possible, but I'm not too worried, if the programming process is a little cumbersome, if the SOICbite experiment doesn't work out.
I'm wondering what the minimum input voltage is. The description only says max. 6.5V input voltage from the battery, but does not say what the minimum is. Both the nrf24l01+ as well as the atmega328P work with 3.3V, so if I use three AA batteries, that should be fine, right? I suppose using two AA batteries is not enough?
Hi @blackchart,
Unfortunately, all devices are sold out. Further production is possible only when ordering more than 10 devices (in this case, I also can modify the device to suit your needs).
@TRS-80 There's an argument for putting two different value capacitors near the nRF24L01 (or whichever radio you're using). A 0.1uF bypass cap to help filter out noise, and a higher value cap as insurance against possible battery ESR and/or inductance from possible long battery leads/traces. For example: https://www.openhardware.io/view/480/Compact-nRF24L01-Pro-Mini-Bottom-Shield#tabs-design
Do you have interest to try OH2 together with MySensors Ethernet Gateway to get working?
I do not have enough force to push developers to make this happen. At the moment there is some problem on this, because full control is not possible. I think that MySensors Serial Gateway is working with OH2, but I don't like to use it. I like to connect my devices into LAN not cabling via old fashioned way using serial wires.
