TiCK-EMB - $35
This design offers board mounted keyline and keyer jacks, a board mounted pushbutton switch, a board mounted lithium battery (for keyer memory backup), and circuitry to protect against static electricity and stray RF signals.
Summary of TiCK-EMB Kit Features
- On-board 3v lithium cell, for memory/parameter backup
- Support for 7-25v DC input, for primary power supply
- Low Drop Out / Low quiescent current 5V regulator (conserves power)
- Support for protection against static discharge
- Support for enhanced RF immunity
- Support for board-mounted Keyline & Paddle jacks
- Support for board mounted pushbutton switch
- Small size: 2"x2.5"
We received a LOT of feedback on the volatility of the TiCK's memory, so we designed a 3v lithium cell holder on the new TiCK-EMB board. Now you can power cycle the TiCK, and the 3v cell will power the TiCK's memory, so the memory messages will be there when powered up again! Since the TiCK chip only draws 1 uA when in sleep mode, the 3v lithium cell will last a LONG time. The board allows for operation with a primary 7-25v DC input, and uses a diode to isolate this supply from the onboard battery. The EMB board is approximately 2"x2.5" and is a single-sided, tin plated, silk-screened board.
The kit includes: TiCK-4 Keyer chip, enhanced TiCK circuit board, 8 pin socket, 4 resistors, 6 capacitors, 1 diode, 1 piezo audio transducer, 2 board mounted jacks (keyline & paddles), lithium cell holder, 3v lithium cell, board mounted normally open momentary switch, 9V battery clip, and 5v regulator.
