3-pin 5V step-up (boost) switch-mode regulator module
A small module that accepts a 0.9-5V DC input and produces a 5V DC output at up to 480mA.
It has the same footprint as many linear regulators and a three-pin right-angle header can be soldered to it (not included) to mount it in many locations that are designed for a linear regulator.

3-pin 5V step-down (buck) regulator module
A small module that accepts a 6.5-40V DC input and produces a 5V DC output at up to 1A.
It has the same footprint as many linear regulators. A three-pin right-angle header comes pre-soldered on it, allowing you to mount it in many locations that are designed for a linear regulator.

ATtiny45V-20PU programmed for the 2m VHF FM Test Signal Generator [0610723A.HEX]
An Atmel ATtiny45-20PU 8-bit microcontroller programmed with the firmware for the 2m FM Test Generator.
Note that the EEPROM is programmed with a default set of custom frequencies. You need to program it yourself if you want different custom frequencies.
