💬 Simple compact RS485 node (ATmega328 + MAX485)
-
Soon a new revision of the board with the possibility of installing memory for OTA and fix some components footprints will be ready.
-
@dzjr I can upload new revision, but it still not tested in hardware, only ready to place order for PCB!
@cabat
sorry I'm new to ordering PCBs hence maybe the stupid question ..
If I order the PCB do I get the separate PCB without SMD components?
or are the SMD components already on the PCB?Soldering "normal" components is going to work, and I also have experience with it, but SMD components will be a new challenge, not that I don't want to, but I don't have the right stuff (yet).

@dzjr Ordering PCBs you will get only pcb, without components (no matter - SMD or TH). You may use PCB assebling service like JLCPCB or other, or you may solder SMD components yourself, it is not so hard, as you can think.

@cabat I have ordered four pcb's and the other components (resistors, capacitors, max485 and voltage regulator in china) and the ATmega at a german webshop.
do you have some advice for smd soldering?

@dzjr I am using simple solder station like 936 with 900M-T-I iron tip, first solder the MCU and pin-headers, programm with USBASP using pads SCK, MISO, MOSI, RES, VCC ang GND, then solder other components (MAX485, resistors and capacitors).

@cabat unfortunately i am still waiting for the pcb's so i could try it unfortunately ...
Still listed as "In Fabrication" hope it comes soon ...in the meantime I have received all parts

@cabat The PCBs have been delivered !!
only now the weather is very nice here, so I don't feel like hanging out in the workshop ...
I'll let you know when I'm ready!
