This is and introduction to Moteino, a low cost wireless Arduino clone that I designed for my own projects, but since some people started asking about it i decided to try to make it available to others.
Some time ago I started to think of how I could build a simple network of arduino nodes for environmental data harvesting and home automation, but I wasn’t very happy with the existing solutions because they were either not the right size, not battery friendly, I had to hand solder the kits to keep cost low, etc. Ethernet shields are also expensive and running wires around the house was out of the question.
So that’s how the Moteino concept was born. It’s based on the ATMEGA328p and has all the pins exposed, runs at 16Mhz, 3.3v. On the bottom it has a footprint for the RFM12B transceiver which is an excellent alternative to XBee radios, which are at least 3 times more expensive.
UPDATE: There’s now a dedicated All-About-Moteino page.
UPDATE: I posted some details about a Leonardo version of Moteino (based on ATMega32u4). For more details about MoteinoLeo click here.
I know there’s many other arduino clones out there that have similar specs. However most of these arduino clones are either somewhat overpriced, they are bulky, or you have to hand-solder them, which if fun for learning how to solder but is time consuming when you just need a bunch of these assembled. If you need 20 or 30 wireless arduino nodes, the time and money you spend can pile up.
So here are the highlights of Moteino:
- Low cost Arduino clone fully compatible with the Arduino IDE
- Designed for very low power battery operation
- The Wireless version includes an onboard RFM12B transceiver and wire antenna
- Very small size – 1.3 x0.9 inch
- Breadboard friendly header layout allows you to attach female/male header pins on the top or bottom and make shields for it or just use it on the breadboard for prototyping
- FTDI programming header
- Optiboot bootloader for fast programming and no delay startup
- Onboard LED for debugging or visual indication
- Standalone version cost is around $10-12 and wireless version about $16, fully assembled
The onboard radio can act as a transmitter or receiver, and I prefer the 434Mhz version because it has longer indoor range and very good wall penetration, but nothing stops you from using a 915Mhz version. Also if you’re in Europe the 434Mhz and 868Mhz bands are legal, not the 915Mhz.
This is my first revision and I still have some minor tweaks I want to make. But i’ll post updates as soon as i have them.
