Tutorial - SX1509 I/O Expander Breakout Hookup Guide last year

the fritzing diagram for the io test is wrong, button is shown connected to pin 0, but the code says 7
Product DEV-13598 last year

would have been nice if the i2c pinout matched your sensor board (HTU21D)

This design has some serious problems. If a battery is connected with USB connected and the power switch is on then 5 volts is connected to the battery. BAD! The charging LED is always on. BAD! All the LEDS for power, serial in and out are always on, not good for battery power. BAD!

I don' find any info in the user guide about the python interface, does anyone know where to look? Can custom web pages be added to display sensor data? The Sparkfun price is forty dollars higher than digi’s, kind of a high markup!

No public wish lists :(
