A wide range RF detector 50-3000Mhz with battery charger, ATtiny micro controller and SMD.
The RF detector can be used as linear instrument monitor or as threshold/comparator alarm. DipSwitch1-1 setting: On=buzzer on, Off=buzzer off. DipSwitch1-2 setting: On=instrument, Off=comparator. The threshold level comes from 10K trimmer you may set as you like. In comparator/alarm mode the top panel RGB led and the buzzer will flash/beep 3 times when RF signal is greater then trimmer position; additionally, every 10" a single flash of green color led will let you know the comparator is on and working. In instrument mode both buzzer and top panel RGB LED change their level (sound & light) depending of the detected RF power level.
By the way of DipSwitch2-1 and DipSwitch2-2 you may change the colour of the top panel RGB LED: 00=off 01=red 10=green 11=blue.
It is an USB mini connector to recharge the battery from an USB power source, and a small red colour LED, on the side, to show when it is charging.
Inspired from John Bradnam's ATtiny 1614 Project I bought a couple of this microcontrollers to take a new way and enjoy a new adventure, I made MyTiny first testing circuit. Everything is working on my choice to power it at 3.3v. Up to today I tested and verified: digitalRead, digitalWrite, analogRead, analogWrite both PWM and DAC; I provided a serial monitor though pins RX/TX <-> FTDI serial interface and SoftwareSerial library; finally I connected an OLED 128x32 display by the way of SDA/SCL and Wire library. Cool!
To program the ATtiny by the way of an Arduino NANO and IDE please read Bradnam's instructions at above link. Here some of it:
