Arduino "STRONG" versions, with a lot of pins

alowhum Plugin Developer last edited by alowhum
I just discovered these boards, and couldn't find any mention on the forum.

These look fantastic. I am always soldering extra pins onto my Arduinos, as I never have enough 3,3V or 5V and GND pins for the NRF and sensors.

But these cute little boards have a power and GND pin for each arduino data pin!

And you can optionally feed them with a wide range of power: 7 -16v

3.3v Pro Mini board is only $2.50

5v Arduino Nano board is about $4,50
- Comes with extra connector for I2C sensors

I'm usually doing this test for each and every sensor i bought and I can confirm that many of them can work without problems. Sensors like DHT seems to need a delay(500), before call the sensor read function, in order to let him "boot-up" otherwise you will experience communication errors. Sensors connected to analog input, like soil humidity, will not give correct measurement, if the precision is not your must is possible to use pin powering, Pay attention on the max current required for the sensor, if you exceed that the Arduino will be damaged. Measure it before to connect! Radio cannot be powered by digital pin (too much current during transmission). Arduino has also a maximum total current that normally can never be exceeded, special attention to be given if you use radio with PA antenna!

@Yveaux thats what I was thinking about. Thanks for confirming.

@scalz - Right okay, i think i understand this pretty clearly now on the method to go about enabling interrupt to wake the uC. I have just realized that there is a example sketch that uses sleep function for 2 switches, i can use this and modify it to work for 3 when needed. I shall be studying this sketch along with your links later on tonight hopefully. Once i have sent off my deigns to get my Rev2 remade i will focus my attention to making sure i completely understand the method of this sleep with interrupt function. Thank you for your help guys!

@derrij The console paramter needs to be removed completely. You cannot use the uart for domoticz and as serial console at the same time. https://wiki.openwrt.org/doc/recipes/terminate.console.on.serial

@ricorico94 welcome to the MySensors commu ity! All you need to do when switching from raspberry pi gateway to ethernet gateway is change the "hardware" configuration in Domoticz. However, if you are just starting out, don't use this gateway. It works for MySensors 1.x only. Use the new raspberry pi gateway instead.

Well the replacement regulator datasheet says that pin 5 its not connected to anything so I'm assuming that it doesn't matter. With regard to the PCB, I don't know the answer to that and didn't really consider that. I don't have the actual schematic but my understanding is that all Arduino Mini Pro's are made from the same schematic so if so, pin 4 per the schematic is "bypass" and is not attached to anything on the PCB.

@mfalkvidd right, I was thinking of updating RFM69 wiring diagrams on https://www.mysensors.org/view/171#rfm69-&-esp8266 , but for how the radio module go I was interested in the rfm96 range / reliability to see how it goes. Anyway I will look for futures updates on the forum.
