Yes, you could but it's still kinda overkill for just a bunch of sensors and actuators. With limited soldering a Wemos D1 mini would do a much better job. Use the raspberry as an IoT home server to push the sensor data to.
- voltagex_ 10y agoThe D1s are a pain because they're 3.3v and all of the boards you want to use with them are 5V
- soneil 10y agoPi isn't 5v-safe either. Takes a 5v supply, but 3.3v logic.
- zild3d 10y agoThis is a legitimate complaint at the moment, but with more and more development boards going 3.3v it just means you should always have logic level converters on hand. Luckily they are readily available, quite cheap, and small
- voltagex_ 10y agoI'm pretty new to Arduino and the ESP8266, but doesn't this involve breaking out all the pins to another board to do the level conversion? I was hoping there'd be a converter in shield form.
- zild3d 10y agoAh yes, I am not aware of a logic converter shield at the moment, most are in an IC or a small breakout board like the sparkfun below. I tend to avoid shields in projects as they are more expensive, take up more space, and not as flexible (can't be used as easily with another board e.g. teensy 3.0 vs arduino uno) https://www.sparkfun.com/products/12009 https://www.sparkfun.com/products/12009
- stevekemp 10y agoI keep reading this, but I power all mine with 5v phone-chargers via the mini USB socket. There are output pins for 5v and 3v so you can choose the appropriate power for your display/whatever. I've seen nothing go wrong.
- voltagex_ 10y agoThe ESP8266 is somewhat flexible with what voltage it'll accept, but it's not recommended
- peter_retief 10y agoI am doing the soldering at present, for a little bit more money i get a lot more possibility
