DL6F Issues

Special Assembly Instructions

• solder mask on large pad adjacent to XX1, XX2, XR1 needs to be partially removed so that crystals can be soldered to PCB

• trace connecting pads of SH1 needs to be cut

• 2 pins of SOT-523 diode should be soldered SH1

• 3rd pin of SOT-523 diode has jumper wire that connects to CD1 far side pad

• push button switch is not populated

• Use BAT54CT-FDICT-ND for SOT-523 diode

SD / MMC Requirements and Test Results

The datalogger requirements:

• SPI mode of operation.
• 3.3V (+-5V) operation
• full sized SD/MMC (reduced size not tested)

The datalogger and firmware has been tested with 4 types of SD and MMC cards with a range of sizes from 32 to 128mB and is believed to work with all. The firmware in was unable to operate with two cards - however a commercial card reader and Windows 2000 also failed these cards.
