A tiny board that connects to a 5-pin GPS module (ublox Neo 6M / 7M) and provides the Pi with time and an on-time marker for precision synchronisation (for e.g. a Stratum 1 NTP server. The board mount...
Now with terminations on PPS inputs; removed power (3V3) from PPS connections. Quality of PCB is excellent, as always.
A TH sensor (AHT25, DS18B20) built using a Pi Pico as the controller
A simple controller for a hot yoga studio.
An adapter (SMA male - female) that provides 50 ohm termination of a signal and also taps off the PPS signal (buffered) and then presents the output for use as an NTP refclock.
Pi5 side mount daughter board with 5V1 6A power supply that exposes 4 UART interfaces (2 TTL, 2 RS232) and the SPI1 interface.
Revision 2 of the hardware
Excellent quality board! Thanks.
Now only one connector (communication and power is combined). Quality of PCB is excellent, as always.
A sensor for measuring and displaying (ePaper) temperature and humidity. The work done by PCBWay was excellent. as always.
Converts a digital signal into something that can switch a small relay. Has the required flyback diode.
Revision 1 of Pi 5 daughter board - added PPS inputs and LED indicators.
Revision 10 of this board. PCBWay service was excellent, as always.
Using a AHT25 sensor and a Waveshare ePaper display. PCB quality very good as always!
