This is an old revision of the document!
This is an unassembled kit and requires basic soldering. This is designed for use with the Digispark development board, which is not included.

NOTE ON HEADERS: Basic Robot kits were supposed to ship without stackable headers and with a 1×40 pin male header strip. Many shipped with the stackable headers instead - we encourage you to use some extra male headers from another kit to complete the Wings Kit and then use the stackable headers for any Pro kit you have (you end up with a free set of stackables!) - if you don't have any male headers to spare, please contact us so we can make it right.
Soldering: If you are new to soldering we recommend the following tutorials: Soldering Basics (http://www.sparkfun.com/tutorials/106) and Soldering Crash Course from the folks at Sparkfun (http://www.sparkfun.com/tutorials/354). How to solder from the Curious Inventor: http://store.curiousinventor.com/guides/How_to_Solder
Adafruit has this excellent guide that starts with the tools needed and then shows detailed pictures, including some of the common problems that beginners experience (http://learn.adafruit.com/adafruit-guide-excellent-soldering)
We assume for these assembly instructions that you know the basics of thru-hole soldering. If you don't check out the links above, these boards are very easy to solder - we promise!
Check that you have all parts listed above - they may be located in different bags or even loose in the package.
Prepare the shields:
Solder the female (non-stackable) headers to your Digispark Pro.
Assemble the Wings Kits - using the male headers from the BLE, BT, WiFi Kit or extra ones - per the instructions here: http://digistump.com/wiki/digispark/tutorials/wings
Assemble the BT, BLE, or WiFi kit (using the correct tutorial for that kit) if applicable - using the included 9 pin stackable headers and the extra 3 pin female header.
Cut the two approx. 14” lengths of wire in half, so you have two of each color. Strip all ends of the wires. Solder two wires (one of each color) to each motor, on to the little copper colored metal tabs. Apply a fair amount of solder, and be careful, the tabs are somewhat delicate and can break off the motor.
Find the two metal blocks in the hardware bag and the four longest bolts. Pass the bolts through the motor housing as shown - and through the block - put nuts on the end of the bolt that comes through the block and tighten.
Repeat for the other motor, flipping the side the two holes on the narrow top of the block are on, so that they line up with the holes in the acrylic when the motors are mounted as shown.
Mount the motors to the acrylic base as shown, using two (per mount) of the short pan head screws. Thread each screw in a little, and then tighten alternating between the screws - this will ensure they are able to tighten despite the natural variances in acrylic.
Carefully press the wheels on to the motors.
Attach the 4 brass standoffs to the swivel wheel using 4 nuts.
Attach the swivel wheel assembly as shown to the Acrylic, using 4 pan head screws.
Attach the battery holder as shown using two pan head screw going down through it and the acrylic into two nuts. You will have to push the screws down with a screwdriver, while holding the nuts in place to get them to “bite” and tighten.
Mount the Motor Driver board to the Acrylic base using one of the thinner screws and smaller nuts.
Mount the Digispark Pro board to the Acrylic base using one of the thinner screws and smaller nuts.
Non-Basic Kit: Attach the BLE, BT, or WiFi kit to the Digispark Pro and then the Wings shield on top of that.
Basic Kit: Attach the Wings Shield kit to the Digispark Pro.
Attach the wires from one motor to the screw terminals on the Motor Driver labeled “A”, and from the other to the ones labeled “B”
Attach the jumper wires from the VCC and GND pins of the Motor Driver to the VIN and GND screw terminals on the Wings Shield. Also attached the black wire from the battery holder to the GND terminal on the wings shield. And the red wire to the VIN terminal on the Wings shield. It may be easier to solder the battery wires to the pins of the jumper wires before putting them both in the screw terminal together.
Attach the jumper wires from the A-A and A-B pins on the Motor Driver to Pin 0 and Pin 2 of the Wings shield, respectively.
Attach the jumper wires from the B-A and B-B pins on the Motor Driver to Pin 1 and Pin 5 of the Wings shield, respectively.
Use tape, glue, or zip-ties (not included) to organize the wires if desired.
Insert batteries (before plugging the Digispark into the computer, or remove the wings shield before plugging it in!) - and then plug the Digispark Pro into the computer and upload the test code. If the wheels are not moving the same direction then flip the wires for one motor going into the motor driver. If both wheels are going the wrong way (backward instead of forward), then flip both sets.
Your Robot is Complete!
