Electronics for IoT, Prototyping & DIY

The ATTINY88 Micro Development Board is a compact, Arduino-compatible microcontroller board powered by the Microchip ATtiny88 running at 16MHz. Designed as a direct upgrade from the popular Digispark ATtiny85, it delivers 28 GPIO pins, 8 analog inputs, and hardware I2C and SPI -- all in a tiny, breadboard-friendly Nano-style form factor with convenient Micro-USB programming via the built-in Micronucleus bootloader.

⚡ Big Upgrade from ATtiny85: 28 GPIO pins (vs. 8), 8 analog channels (vs. 4), plus hardware I2C and SPI -- all programmable directly from the Arduino IDE over Micro-USB. No external programmer needed.⚡ Key Features

ATtiny88 at 16MHz -- 8-bit AVR RISC microcontroller with external crystal for reliable timing
28 GPIO Pins -- Massive I/O expansion over the ATtiny85\'s 8 pins
8 Analog Inputs (A0–A7) -- 10-bit ADC resolution for sensors, potentiometers, and more
Hardware I2C & SPI -- Connect OLED displays, sensors, SD cards, and other peripherals directly
Micro-USB Programming -- Upload sketches via the built-in Micronucleus bootloader -- no external programmer required
Arduino IDE Compatible -- Use familiar Arduino sketches, libraries, and workflow
Compact Nano-Style Form Factor -- Breadboard-friendly dual inline headers
Onboard LED on Pin 0 -- Ready for immediate testing out of the box
Onboard Voltage Regulator -- Accepts 7–12V on the VIN pin

🔧 How It Works

Install the Digispark/Micronucleus USB driver on your computer (Windows requires manual install; macOS and Linux typically work automatically).
Add the MH-ET LIVE board manager URL to your Arduino IDE and install the board package.
Select \"MH-ET LIVE Tiny88 (16.0MHz)\" as your board in the Arduino IDE.
Write your sketch and click Upload -- do NOT plug in the board yet.
When the IDE displays \"Please plug in the device...\", connect the board via Micro-USB.
The upload completes automatically and your sketch begins running immediately.

💡 Tip: The upload sequence is the opposite of most Arduino boards -- click Upload first, then plug in the board. The Micronucleus bootloader has a 5-second window to accept uploads after being connected.⚠️ Important Notes

No Hardware UART: The ATtiny88 does not have a built-in serial port. Use the SoftwareSerial library if your project requires serial communication.
Limited PWM: Only 2 pins (D9 and D10) support hardware PWM -- fewer than a standard Arduino Uno.
Limited Flash: Approximately 6 KB available for sketches after the bootloader. Keep code lean and avoid large libraries.
Small EEPROM: Only 64 bytes of EEPROM -- significantly less than the ATtiny85\'s 512 bytes or the ATmega328P\'s 1 KB.
USB Pin Conflict: Pins D1 and D2 are shared with the USB interface. Avoid connecting components to these pins that could interfere with programming.
5V Logic Only: All I/O pins operate at 5V. Use a level shifter when connecting to 3.3V devices.
Header Pins Require Soldering: The included header strips must be soldered to the board for breadboard use.
