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:
*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.
- 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
