This is little board I made to help me with ATTINY chips projects.
It has 6 pin USBASP input and 4 pin headers for each of the pin of the chip times 3, which makes it easy to connect oscilloscope and put it on breadboard in same time and still have pins to connect to it external device. Also it has both SOIC8 and DIP8 packages support.
Tiny little helper.
TinyKnob is a rotary encoder with a USB interface based on the ATtiny45/85 and the V-USB software-only implementation of USB1.1 devices on AVR microcontrollers (https://www.obdev.at/products/vusb/index.html). The example code implements a volume control knob for PCs which works without installing any driver by acting like a generic HID device.
ATtiny controlled and LiPo battery powered MP3-Player using the DFPlayerMini-module featuring:
- Micro-SD-card slot,
- battery charging and protection circuit,
- battery level detection,
- OLED display,
- on/off switch,
- volume control,
- 3 push buttons to control the player.
You can directly connect a 3.7V LiPo battery and a 3W/4Ohm speaker to the board.

The ATtiny85 USB Phone Charge Guard controls and monitors the charging of phones and other devices. Voltage, current, power and energy are constantly measured via the INA219 and compared with the user limit values. It cuts off the power supply via a MOSFET when a condition selected by the user is reached. The user settings are saved in the EEPROM.

Simple USB ISP programmer for Atmel AVR microcontrollers based on the ATtiny45/85. More information can be found at https://dicks.home.xs4all.nl/avr/usbtiny/. Windows users may need to install a driver: https://learn.adafruit.com/usbtinyisp/drivers. Of course this is not necessary for linux and mac users.
Display-Module created and developed for Eurorack-Synth-Modules.
Digit height: 5.03mm !
Module size (w x h): 20.7mm x 22.86mm
For following controllers:
Example code using Attiny84:
ATtiny85 controlled FM radio with RDS (RDA5807) and integrated audio amplifier (XPT8871). You can directly connect a protected li-ion battery, a 3 W / 4 Ohm speaker and an FM antenna.
See how I've made my own PCB for the well know circuit of ATtiny85 Arcade game. Here you will have the schematic, part list, step by step of soldering components, how to burn bootloader and how to upload codes for different games to the ATtiny85. I know this is nothing new and you have more here on the original GitHub post. But I hope you will learn something new.

What if multiple lamp groups need to be controlled in an existing single lamp group (Multiway switching circuit) situation.? The cabling (1 line – hot - wire and two - nonhot - wires) between switch(es) and the lamp group is existent, buit-in walls and/or ceilings in most cases and this cabling is not possible to be modified or extended.
This circuit offers a safe and flexible possibility to co...
