ATtiny Dev Board / Tinyduino

This is an AT tiny Dev. Board. Designed for the AT tiny line of microcontrollers from Atmel. Its made to be small, simple to build and easy to use.
This board has following features:
– Female headers for easy prototyping
– Build-in 1A 5V voltage regulator
– 8-Pin socket to change out microcontrollers
– ISP-Header for programming
– Power select switch, using voltage regulator or the USB power of the programmer
– Reset button
– Power on LED

Step 1: Required Parts / Tools

1x Perforated PCB
2x 1×4 Female headers
2x 1×3 Male pin
2x 100nF Ceramic capacitor
1x Resistor 10k ohm
1x Resistor 220 ohm
1x Slide Switch (SPDT)
1x Momentary push button
1x LED 3 or 5mm any color you like
1x 8 Pin DIP socket
1x 7805 Voltage regulator
1x Terminal block
1x Some wire
– Soldering iron
– Solder
– Helping Hands
– Box cutter
– Wire stripper
– Wire cutter
– Tweezers
– Pliers

Step 2: Score and Snap Your PCB

My PCB was already 18 pads wide so I only need to shorten the PCB to 11 pads long, I did this by counting down the 11 rows and started to score the 12 row with a box cutter (BE CAREFUL). After 5 to 10 passes I snapped the board in half. If your board is wider as mine you need to do the same for the other side too but this time 18 pads instead of 11. If done correctly the board should look like the board in Step 1

Step 3: Bend and Solder Resistors

The 10k ohm resistor is bend so that it spans 4 holes. And the 220 ohm resistor is bend to span 5 holes. Solder them in as seen in the picture. And use the PCB layout as reference. Its helpful to own Helping hands so its easier to solder, it’s best to solder one leg first then applying pressure to the part and reheat the joint so that the part aligns with the PCB. Now you can solder the second leg. You maybe want to use some kind of tool to apply pressure since the part could get hot quite quickly.

Step 4: Cut and Bend Jumper Wires

Take some wire which fits through the holes of the PCB and cut to sections of 2 cm (0,8 inch) in length. Bend them so they span 4 holes. Use pliers for best results.
