This design is made for coupling an ATTiny84, 3 sensors and a radio transmitting unit. However it can be "hacked" to any DIY project using a tiny84 ! This is the main board of this project. It's sold naked.
It was first designed to :
Be battery powered with a CR2032 or 14500 : both an AA battery holder and a SMD CR2032 pattern are included
Receive a 433 or 315 MHz radio transmitter. 2 pins ordering are available to fit most of the commercial transmitters
Solder an SMA Tx connector
Interact with up to three sensors (Data Vcc Gnd), with Vcc controlled by on pinout of the microcontroller
And last but not least, blink a LED !
The design also includes the place for a diode and a capacitor. It doesn't include a voltage regulator and so is powered from the battery voltage.
