RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
| Substance | Concentration |
| Lead | 0.1% |
| Mercury | 0.1% |
| PBB (Polybrominated Biphenyls) | 0.1% |
| PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
| Hexavalent Chromium | 0.1% |
| Cadmium | 0.01% |
| DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
| BBP (Benzyl butyl phthalate) | 0.1% |
| DBP (Dibutyl phthalate) | 0.1% |
| DIBP (Diisobutyl phthalate) | 0.1% |
The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".
RS Components has taken all reasonable steps to confirm this statement. Information relates only to products sold on or after the date of this certificate.

Product Details
Adafruit Feather 32u4 Development Boards
The Feather 32u4 is a range of development boards from Adafruit. They are powered by the Atmel ATmega32u4 microcontroller clocked at 8 MHz with 3.3 V logic. This chip has 32K of flash and 2K of RAM and built-in USB. As a result it has a USB-to-Serial programme and debug capability built in and it can also act like a mouse, keyboard, USB MIDI device.
This chip is supported in the Arduino IDE and can run nearly every sensor/library available.
The Feather is perfect for small or portable projects. There is a connector for 3.7 V Lithium polymer batteries and built-in battery charging circuit which you can use to measure and monitor battery levels. Lithium Polymer battery and USB cable not included.
Supplied fully assembled and tested, with a USB bootloader that lets you quickly use it with the Arduino IDE.
Adafruit Feather 32u4 Basic Proto Board
The Adafruit Feather 32u4 Basic Proto has all the basic features shared by all the Feather 32u4 range together with a small prototyping area. In simple projects where you would like to attach a button or sensor, you could skip on a breadboard and wire it directly on to the board.
