Step 2 – Connect Main Right PCB to Arduino

Parts:

  • Main Right PCB
  • Arduino
  • 13x Male to Female header cables
  • 2x 7 pins Stackable Bend Male Headers

To do:

  • If you place the Main Right PCB in front of you, you can see a 13 pins headers on the top right. Pins are enumerated from 0 to 12, starting from the left.
  • Please note that the wires colors are usually different than those in the photos.
  • Note that you probably want to do this with the Main Right PCB below (or to the left of) the Arduino rather than above (or to the right); if the jumper cables point away from the Arduino rather than towards its center, you won't be able to fit it into the frame properly. See the photo below the table.
  • Connect Arduino to the Main Right PCB according to the following table:
Arduino pin Main Right pin
GND 12
13 0
12 1
11 2
10 3
9 4
8 5
7 6
6 7
5 8
4 9
3 11*
2 10

*Note the pattern change of the pin number for the Main Right PCB

Warning: failing to correctly connect the PCBs according to the previous table may result in permanent damage to Arduino.

Step 3 – Connect Main Left PCB to Left Vowels PCB

Parts:

  • Main Left PCB
  • Vowels PCB
  • 3x Female to Female header cables

To do:

  • If you place the Main Left PCB in front of you, you can see a 3 pins headers on the bottom right. Pins are enumerated from 0 to 2, starting from the left. Similarly, on the Vowels PCB, you can see a 3 pins headers on the top, and pins are enumerated from 0 to 2, starting from the left.
  • Connect the Main Left PCB to the Vowels PCB according to the following table:
Main Left pin Left Vowels pin
0 0
1 1
2 2

Warning: failing to correctly connect the PCBs according to the previous table may result in permanent damage to Arduino.

Step 4 – Connect Main Right PCB to Right Vowels PCB

Parts:

  • Main Right PCB
  • Right Vowels PCB
  • 3x Female to Female header cables

To do:

  • Connect the Vowels PCB to the Main Right PCB according to the following table:
Main Right pin Right Vowels pin
0 0
1 1
2 2

Warning: failing to correctly connect the PCBs according to the previous table may result in permanent damage to Arduino.

Step 5 – Connect Main Left PCB to Main Right PCB

Parts:

  • Main Right PCB
  • Main Left PCB
  • 1x White Alarm cable
  • 8x Self-threading screws (2,9mm x 13mm)

To do:

  • If you place the Main Left PCB in front of you, you can see a 11 pins headers on the top right. Pins are enumerated from 0 to 10, starting from the left. Similarly, on the Main Right PCB, you can see a 11 pins headers on the top left, and pins are enumerated from 0 to 10, starting from the left.
  • Connect the two PCBs with the white alarm cable according to the following table:
Main Left pin Main Right pin
0 0
1 1
2 2
3 3
4 4
5 5
6 6
7 7
8 8
9 9
10 10

Warning: failing to correctly connect the PCBs according to the previous table may result in permanent damage to Arduino.

Step 6 – Assemble Right Frame

Parts:

  • Electronics
  • 1x Right Vowels keys
  • Right Frame
  • 3x Self-threading screws (2,9mm x 6mm)
  • 2x Self-threading screws (2,9mm x 9mm)
  • 6x Self-threading screws (2,9mm x 13mm)

To do:

  • Now that you have all the electronics connected, you can try to test that they work correctly by plugging them in with a micro USB cable. If you are a Windows user, don't forget to install the Arduino IDE before connecting Stenoboard, as explained at the end of this manual. Wait till the two LEDs light up, and than try to press some keys. If it works, you will see some letters appears on the screen for all keys, except the ones on the leftmost column of the left keyboard.

  • Place Arduino on the bottom of the Right Frame and tighten the 6mm screws. IMPORTANT: DO NOT tighten them too much but very lightly or the screws will strip the holes; please follow this advice for all screws in this and subsequent steps. If you do strip any hole, you can put a dab of glue inside the hole before tightening the screw.

  • Place the Right Vowels PCB in the Right Frame and tighten the 9mm screws. Please note that the casing has an overhanging lip and there is more room underneath for the vowels PCB.
  • Do the same for the Main Right PCB with 4x 13mm screws. It might be useful to insert two of the screws very loosely (just screwing in a few turns so they are mostly sticking out a long way) to help anchoring the board and to make it easier to get the wires into place. Please use care when tightening these screws to avoid breaking them.
  • Push all the cables below the top of the frame.

  • Place the Vowels keys in the frame and tighten the 2x 13mm screws.

Step 7 – Assemble Left Frame

Parts:

  • Electronics
  • 1x Left Vowels keys
  • Left Frame
  • 2x Self-threading screws (2,9mm x 9mm)
  • 6x Self-threading screws (2,9mm x 13mm)

To do:

  • Place the Left Vowels PCB in the Left Frame and tighten the 9mm screws.
  • Do the same for the Main Left PCB with 4x 13mm screws.

  • Place the Vowels keys in the frame and tighten 2x 13mm screws.

Step 8 – Final assembly

Parts:

  • Frames assembled in Step 6 and Step 7
  • 2x Consonants keys
  • 2x Number keys
  • 8x Self-threading screws (2,9mm x 13mm)

To do:

  • Place the Consonants keys and Number keys on top of the left frame and tighten the screws, and do the same for right frame. Make sure that wires and cables do not touch the keys above them, otherwise some of the keys may require more force to trigger them.

Congratulations! You now have an assembled Stenoboard and can connect it to your PC.

If you are a Windows user, don't forget to install the Arduino IDE before connecting Stenoboard; if you don't, it is possible Stenoboard may only work in NKRO-emulation mode and it may not be possible to update the firmware in the future. If that happens to you, you can fix it by changing to a different USB port, or by restoring your computer to a previous restore point.

And finally, don't forget to check the Stenoboard User Manual!
