Fcal Circuits
Most Fcal applications will require an external circuit to
convert sensor or other input voltages to frequency. A
collection of such circuits is provided with Daqarta, in the
Documents - Daqarta - Circuits folder.
Each circuit has been designed to run from a single 9 V
"transistor radio" battery. (See also
9 Volt Battery Connectors.) Standard, low-cost parts have
been used throughout.
See Printed Circuits for a general overview of construction
options, including Printed Circuit Construction and
professional board fabrication.
