  • Originally posted a comment about wall wart difficulty. Have recently discovered that my unit was manufactured with the u.FL mounted “backward” - the center pin is connected to the “NC” pad instead of the signal input. Turns out that not having an antenna connected causes BAD things to happen, like processor resets when trying to access WiFi. Check the continuity if you’re planning on using the u.FL connector.

  • Quick “Hidden Gem” from the Data Sheet - Unlike many I2C devices, doing a multiple-byte read (e.g. to read all x,y,z values) does not automatically advance the register pointer, unless you set bit 7 in the register address. Reading 6 values from register 0x28 returns you the low order x-acceleration byte 6 times - reading 6 values from register 0xA8 will return the 3 axis 16 bit acceleration values.

  • Whoa!!! These aren’t only analog inputs – A4 and A5 are used as SCL and SDA in the I2C Wire Library. Does this mean that the Pro Micro has NO WAY of supporting any kind of I2C interface? If so, then this is a reasonably serious limitation that should be pointed out on the product page!

  • If “Z” is followed by “AA” and “AB,” then a Saturn V first stage is an “AF”

  • Appears that Epson Toyocom is about to start production of a 6-axis MEMS Gyro/Accelerometer:

No public wish lists :(
