Discover specially designed development boards that offer the stability of 8-bit AVR architecture, from wearable e-textile products to fingertip-sized compact systems.
Today, the foundation of the open-source electronics prototyping world is built on AVR microcontrollers, developed by Atmel, now part of Microchip.
These chips with 8-bit RISC architecture are known for their low power consumption, instant response times, and hardware stability.
If you want to combine electronics with fabric, LilyPad-compatible boards with rounded shapes and large connection holes are a suitable option for you.
Powered by ATmega328P or ATmega32U4 processors, these boards are sewn onto clothing using conductive threads instead of breadboards or soldering.
They provide a strong foundation for making illuminated jackets, smart gloves, or sports shirts that measure pulse.
If using a standard development board is physically impossible in your project, for example if you are designing a ring or a mini keychain, ATtiny85-based development boards come into play.
These boards are only about the width of a USB port, yet despite their 8-pin structure, they can perform digital/analog reading and support I2C/SPI protocols.
AVR-based special development platforms such as TinyLab, where all sensors are gathered on a single board without cable clutter, are especially useful for coding classrooms.
If you want to make a quick start in education and try different hardware combinations, you can also check our Kits Based on Arduino category.
You can review the table below to choose the most suitable model according to your project’s physical limitations and pin requirements:
| Hardware Model | Core Chip | Key UX Feature | Ideal Use Case |
| ATtiny85 Development Board | ATtiny85, 8-bit | Direct USB connection, mini size | Simple projects with limited space |
| LilyPad, ATmega328P | ATmega328P, 8-bit | Large pads suitable for sewing with conductive thread | E-textiles, smart clothing |
| LilyPad USB, ATmega32U4 | ATmega32U4, 8-bit | Built-in USB communication, keyboard/mouse simulation | Wearable HID devices |
| TinyLab Maker Board | ATmega328P, 8-bit | All sensors combined on a single board | Coding education, wireless R&D |
Working with niche AVR boards such as ATtiny85 and LilyPad requires different hardware knowledge compared to standard boards.
At Robotistan, we help solve the most common user issues in advance:
Yes, it is technically possible. LilyPad boards and conductive threads are suitable for gentle hand washing. However, before washing, you must definitely disconnect the power going to the battery, and you should not power the system again before the board is completely dry to prevent the risk of short circuit.
ATtiny85 boards can be programmed with C++ through the Arduino IDE. To do this, simply add and install the Digistump/ATtiny package URL in the Board Manager section of the IDE and install the board driver on your computer before first use. Relevant links are available on our product pages.
Both chips are 8-bit processors with AVR architecture. The biggest difference is that the ATmega32U4 chip includes built-in USB communication hardware. This allows a 32U4-based board, such as LilyPad USB, to identify itself as a HID device such as a keyboard or mouse when connected to a computer.
