There is no write protect on these chips..http://ww1.microchip.com/downloads/en/D ... 21072G.pdf
3.3V to Vcc pin 8, Gnd to Vss pin 4.
SCL and SDA to Carambola, tried with and without 100ohm.
Tried different adresses, A0,A2,A3 to Vss or via 1k pullup to Vcc.
Will the carambola break if the 24LC32 was powered by 5V instead of 3.3V (I could have made a misstake on late night..)
Other posts here states that the RT3050 is 5V tollerant, other parts says no..
