To solve the problem I connected the two internal i2c pull-up resistors to 5V. You need steady hands to cut the copper layer between R3 and C1.
When done, solder a wire between R3 and 5V (on connector J1).
That's all ;-)

RE: M5Unit Miniscale Questionsposted in Units
As spiff72 also pointed out, negative weights are displayed as positive. That's quite confusing for our students. For now, I've addressed this by using the raw ADC data as a zero point after an offset (tare). If the value during a measurement is greater than the zero point, then the value of 'scales.getWeight()' is positive. If the value is smaller, then I multiply 'scales.getWeight()' by -1.
I hope that issue is solved in the next library update.
