      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).

      @gohan said in Arduino Pro Mini Shield for RFM69(H)W: If I remeber right that pin is used as input so the RFM69 is not receiving any 5v signal. In addition there are people claming they have the RFM69 module working on 5v on data pins and 3.3v on vcc, but I hardly suggest to do it. thank you just what i thought . about direct 5v on data...well... i seen a big red sign saying n :DONT do it! lol Level converters are so cheap...that i ordered 5 or 10 thoguether with rfm69 board. sorry about hijack this topic, i though i was on general discussion

      Hi @berkseo. Thanks for the suggestion, but could you describe in more detail? As for my TODO list, there is already a task to add 485 interface to the gateway. My latest device "xRoom" have this interface. ps/ Where have you gone? I have been working on "xRoom" shield. A small announce: Do you remember the discussion about multinode? So, it will be available soon))

      Hello. Are these modules still in operation? As it is already an old project I would like to know the reliability and energy consumption? Thanks

      Hi, nice projet. I am very interested in it. But why you are using 5 V and not 3.3 V? The ATmea328 works with 3.3 V too and the NRF have to use 3.3 V. The only restriction on 3.3 V is the clock limitation for the Atmega (8 MHz). But with no crystal it don't care. For example you could use an HLK-PM03 instead of HLK-PM01 and remove the linear voltage regulator. So you get more space an everything have the same voltage level. And another point is, it is recommended to use a capacitor (0.1 Β΅F) to ground for each voltage pin (Vcc, Avcc, Aref).

      @GertSanders ok, strange. standard pin headers fit for me only into FTDI and ICSP pin holes. Into the other two 8 pin rows it does not fit.

      When you read the data sheet correctly you can see, that the distance between the pins is different for a AA and AAA battery holder. That`s why I was asking if somebody can recommend a holder that fits.
