ZXPrinter Shield - $30 + shipping
Connects Arduino to Timex/Sinclair Printers
Open Source Project - software on GitHub
To be clear... this is a product for Arduino enthusiasts.
It is not for Timex/Sinclair Computers... only for Timex/Sinclair Printers.
 |
| ABOVE EXAMPLE: Arduino UNO with ZXPS is taking power from a USB cable, and a temperature and humidity sensor is hooked up to the ZXPS through it's optional Qwiic connector level shifters. |
 ZXPS with basic printer components,plus the optional Quiic/STEMMA and Serial interface components installed. |
 |
| ABOVE: The ZXPS as shipped. The 8 components needed to complete the printer function are large, easy-to-solder thru-hole components. Typical assembly time is 10 minutes. If you are going to interface to a 3.3 or lower voltage I2C sensor, 8 SMDs are included for an optional Qwiic/STEMMA circuit, but this requires good eyesight and surface mount device soldering skills and tools. |
