We are happy to announce availability of SH-ESP32 rev. 2 boards! The new boards include some minor design changes required for component availability, but the most significant change is that the board now comes pre-assembled with the connectors and headers in place! Additionally, the power input and CAN bus connectors are now 3.81mm pluggable screw terminals, making the board even easier to set up!
Would you like to get better temperature monitoring for your boat engine? Are you worried about forgetting to open the water intake seacock? Is the coolant circulation working properly? We have prepared a tutorial that walks you through creating an inexpensive and easy to install but powerful temperature sensing device with the SH-ESP32 development board. The device measures the engine oil, coolant, and wet exhaust temperatures and transmits the data to your NMEA 2000 network or Signal K server.

The COVID-19 pandemic has caused a global semiconductor shortage, caused by partial shutdowns of integrated circuit production facilities due to the global lockdowns early 2020 as well as marked increase in the demand of computers and consumer electronics. As a result, many commonly available chips have become totally unavailable or the price has increased many times over. For example, a common real-time clock chip, DS3231MZ used in SH-RPi cost USD 1.61 in low quantities in August 2020, but now the price has increased to over USD 7 at low quantities, with ship date estimates around May or July, 2022. Some of these components can be easily replaced, but most require at least a partial PCB design with prototype rounds and EMC pre-compliance testing.
