  • I confirm DS1307 work well on 3.3V GPIO with 1K pullup resistors on SDA/SCL, dont forget to unsold SJ2 jumper and supply 5V power. For information my board got 4.7K on SDA/SCL,it’s too much and dont work well. START falling edge on SDA pin is not clear with 4.7K, with 1K signal is perfect on 3.3 V GPIO.

No public wish lists :(
