My project controls up to 6 12V PC fans (3/4 pin) based on the input of a DS18B20 temperature sensor. The CPU is a Pi Pico module. TTL serial communication with the host. The PCBs were excellent, as ...
A Pi Pico intercepts serial communication between a host and a clock. Any priviledged command must be prepended with a password that the user can set using the ILI9488 based touch screen.
Carrier for environmental sensor consisting of Rotronic and Bosch sensors
Excellent work by PCBWay as always. For this board I had to over design it significantly because of component shortages. A much more compact design is possible (using probably less than half the boar...
Thanks, excellent work as always
For evaluation of the Jackson Labs LTE Lite module, mounted on a header (for easy re-use). Buffers signals, allow selection of output (GPS / CPU) to USB, has support for external antenna. I also desig...
Pi 4B daughter board for OpenTTP version 2 (see www.openttp.org). Accepts signals from Signals board.
The much more compact power supply promised a year ago. Components are again available to make this possible.
A board (that is used with the environmental sensor system) that uses a Pi Pico as its brain and exposes two serial ports (with TTL and RS232 options) and an interface for a ILI9488 based touch screen...
Daughter board for Pi 4B. Exposes three GPIO for pulse-per-second inputs and one GPIO for puse-per-second output. UART0 is exposed, with one additional GPIO (for reset signal) to communicate to a disp...
Excellent work as always. Thanks.
Takes an ILI9488 SPI 3.5 inch TFT display (320x480) and a Raspberry Pi Pico to make a nice standalone display solution with plenty of options - your software decides what happens. I wrote a write-only...
Takes 12 V input and provides 5.1V for Pi 4B and 5V for signals, display and USB hub.
Signals board for OpenTTP version 2 (see www.openttp.org). Houses GPSDO (LTE Lite) and GPS Rx (ublox RCB-F9T) and generates / buffers signals to and from IO and Raspberry Pi 4B.
