Project description
v2 uses custom Phoenix Contact #2202994 board layout - designed for Phoenix Contact #2202874 RPi B+ electronic housing.
v2.1 corrects I2C CLK and DATA line crossover bug, USB to UART TX/RX crossover bug, and connectBlue connector pin mirrored bug. Additions are tri color LED for 3G module, Bluetooth antenna hole (RP-SMA pig tail) replaces GPS SMA connector.
v2.2 improves LED operation by connecting directly to GPIO, and shifts the UART bus away from the BT antenna securing hole.
v2.3 improves the SIM card filter, replaces the 2x EMI212 USB filters to NUP4114s, adds the PCB mounted connector for the BT antenna, requiring a uFL to uFL lead for the BT antenna and uses the Carrier Detect Pin (DCD) to control the RED_3G led to indicate when the device is connected to the network.
