    Hi everyone, this is a board for a datalogger I made. Have 10 PCBs on hand. I have the schematic and BOM for those who are interested. Features:

    • 18F13k22 PIC Micro
    • 32Khz external crystal
    • 3 Analog inputs
    • 1 External Vreference controlled via I/O pin for power saving (2.048V)
    • RFM 73 For wireless connection
    • SPI EEprom
    • Automatic switching between battery and USB power
    • USB to UART onboard for local data logging (FT230XS)
    • External connector for UART

    *In sleep mode the circuit only consumes 25uA, but I have not tested this board yet. I originally build these boards from a previous project. Everything should work, but I have not tested out the RFM73 because its new. Im open to any criticism as well. Boards are $5.00, not including shipping (Which should be very cheap).

    If there is enough interest/feedback I can kit these up for those who want a kit.
