Posted October 10, 2026 at 1:42 pm · in Are U.FL and IPEX pigtails the same plug or not? #5

Drawing says MHF4 for main and diversity and MHF1 for GNSS. Glad I asked. Ordered MHF4 pigtails for the LTE ones, U.FL for GNSS, 10 cm each.

Posted September 20, 2026 at 2:05 am · in Uno as an I2C slave sending floats to a Mega and taking commands back: values come out garbled #4

Both boards are 5 V and the Wire library turns on the AVR’s internal pull-ups, so on short wires in one box that’s not it. The bigger problem is three Wire.write calls in requestEvent. Only one write per request works reliably on AVR, and text strings of unknown length make it worse. Put the values in one buffer and write it once. And no Serial printing inside the handlers.

Have you tried the avrdude that comes with the Arduino IDE? Sometimes the Homebrew build is odd.

K is rated to about 1260 °C but drifts and ages fast near the top, especially in a kiln atmosphere. For cone 10 it’s on the edge.
