Version 4 Beaglebone U-blox GPS Cape

February 5th, 2016 No comments

finally got back to building some cape from stock i had on hand with the new boards i ordered many moons ago

just a power input pin fix and some pretty labelling

also in these pictures are the Dallas 1wire temp sensors soldered on, with pins broken out for add on sensors

EEPROM Solder Jumpers WP Bridged enables eeprom write
A0 and A1 Bridge equal Cape Manager Cape Slot Zero  and i2c reference number of 2-0054

in Kernel 4 nvmem changes have become mainline too
so eeprom is now at
for Cape Slot Zero   “/sys/bus/nvmem/devices/at24-1/nvmem”  not the old location of “/sys/bus/i2c/devices/1-0054/eeprom”
i2c bus reference for eeproms also changed from 1 to 2 for reasons…

Beaglebone Black GPS

August 5th, 2014 No comments

given that a straight GPS cape for Beaglebone didnt exist, the only thing to do is to make one with the help of “Wrea”, thanks for that 😀

Based off the Protocape with eeprom from logicsupply.com

making use of the Ublox Max-7Q GPS

Uses Uart4 for serial lines which breakout to pins P9.11 and P9.13

and For Pulse Per Second output from the GPS for NTP it uses pin P8.8 also known as gpio2_3

has jumper for Active GPS antenna power and also a connector for Dallas 1 Wire devices
