nice, your tqfp seems well soldered ;)

Well done! Nice!

Hello,
I have a question about the dimensions. Could you tell me what is the exact measure when fully assembled with nrf24 and with / without goldpins? I have tiny, transparent boxes and curious if I can fit them inside :D

The pcb itself is 21 mm wide and 23 mm long.
With the radio the longest side becomes 30 mm long and 21 mm wide.
Without any pins mounted, the board is just under 5 mm think.
If the dual row angled headers are mounted, the longest side (30 mm with radio) becomes 39 mm.
You will need to add the length of the contacts + wire to that for a complete length.You can also turn the dual row angled header inwards (towards the radio), then the maximum length is still 30 mm.

@GertSanders What is the difference between the v1 version of your stamp size mysensor node that's on OSH PARK and the V2 version that's on your website that you linked to in your OP ( https://www.openhardware.io/view/76/Stamp-size-MySensor-node )?

@NeverDie
None. The plan was to enhance it, so I copied my version 1 to version 2. But then I decided to publish it in Openhardware anyway.
This board is a proof of concept for me.
My next version will have a 8Mhz crystal. The addional powerconsumption is negligable bit the accuracy of timing is much better (and constant, even with dropping voltage).
So the board on OSH Park is identical to the one on Openhardware.io -
Thanks! I ordered it yesterday from OSH PARK, so good to hear.
Have you found something where you really do need the 8mhz crystal oscillator, or were you adding it as a "just in case"?
@NeverDie
I have a use case where I need the clock to be acurate. For realy low power nodes like the ones with reed switches, I also prefer the internal oscillator. -
Goedenavond Gert,
What's your boards.txt file is saying please? I uploaded the bootloader (optiboot_atmega328_08M_038400_D8) and all went OK until I upload my first sketch.
After that I am getting:avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x32 avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x0f avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0xfb avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x32 avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x0f avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0x73 avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0xff avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x32 avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x0f avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0xfbI have to upload the bootloader again in order to upload the sketch - something is clearly not working.

The standard file is just not good. I'll have to find the right one for tqfp chip.
EDIT: copied the "eightanaloginputs" variant in the variant folder, but still can only upload the first sketch after the bootloader, all other uploads are giving me "avrdude: stk500_getsync() attempt x of 10: not in sync:"

@GertSanders Many thanks for your help. This is probably my bad luck, but I have mixed up C1 and R1 mounting them vertically (not horizontally). What a stupid mistake really given that I have checked it a few times. Anyway, now everything is working.
FYG, I looked at your pins_arduino.h - this is a standard one and it is not correct. I corrected the following entries:
static const uint8_t SS = 14; static const uint8_t MOSI = 15; static const uint8_t MISO = 16; static const uint8_t SCK = 17; static const uint8_t SDA = 27; static const uint8_t SCL = 28; #define LED_BUILTIN 8 static const uint8_t A0 = 23; static const uint8_t A1 = 24; static const uint8_t A2 = 25; static const uint8_t A3 = 26; static const uint8_t A4 = 27; static const uint8_t A5 = 28; static const uint8_t A6 = 19; static const uint8_t A7 = 22; -

OK, I will check also on my side :-) Thanks for the feedback. -
