Chip Upgrades
Many upgrades for PicoKeyer and ID-O-Matic chips can be done at little or no cost. Below is a list of possible upgrades:
- PicoKeyer
- White dot chips: No updates available, requires new chip and re-wiring.
- Silver dot chips: No updates available, requires new chip.
- Gold dot chips: Updates available, V3.8 is the latest.
- ID-O-Matic
- PIC16F628A: No updates available, chip upgrade not practical.
- PIC16F648A: Update available, latest is V2.10.
To upgrade your chip, pack it in a box or mailing tube. Please DO NOT ship chips in any type of envelope, padded or not. Chips shipped in padded envelopes arrive badly damaged and cannot be upgraded. Be sure to include your name and address, and a note explaining what you need.
Mail your chip along with $2.00 to cover return postage and packaging. The mailing address is:
Dale Botkin
16624 Elm St.
Omaha, NE 68130-1826
USA
Your chip will be returned to you with the latest available firmware, along with new printed instructions.
If your chip cannot be updated, you can order an upgraded replacement chip instead. The
cost is $5.00 for a PicoKeyer chip, or $7.00 for an ID-O-Matic chip. Note that if your
circuit board uses a significantly older chip version, you may need to modify your circuit
board for the new chip. one example would be upgrading from an older PicoKeyer chip
with a white dot to the latest version. Some minor changes to the PCB would be required.
On the other hand, replacing an older ID-O-Matic chip on a PCB that does not have a crystal
with a new one would require enough modifications that it would not be practical. You can email
me with questions if you are not sure whether your kit can be upgraded.
