RoHS Certificate of Compliance

EU Directives 2011/65/EU and 2015/863 restrict the use of the 10 substances below in the manufacture of specified types of electrical equipment.

Whilst this restriction does not legally apply to components, it is recognised that component “compliance” is relevant to many customers.

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:

PBB (Polybrominated Biphenyls)0.1%
PBDE ( Polybrominated Diphenyl Ethers)0.1%
Hexavalent Chromium0.1%
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 Trinket Microcontrollers (MCU)

Adafruit Pro Trinket Mini Microcontrollers

Adafruit Pro Trinket 5V development board Measures only 38 mm x 18 mm x 2 mm (1.5" x 0.7" x 0.2") (without headers) Provides easy and simple access to the ATtiny85 MCU for development and programming. Small form factor means it can easily be incorporated into prototype/ design.

The pro trinket features Microchip’s ATtiny85 MCU with 8KB program flash, 20 MIPS CPU, 5 PWMs, 2 8 bit timers. Uses the Atmel ATmega328P microcontroller, 28K of flash, 2K of RAM and 18 GPIO.

The Pro Trinket is programmable using the AVRdude and/or the Arduino IDE, and there is a reset button for entering the bootloader or restarting the program as well as LED indication for bootloading. You can also use an FTDI cable to connect to the FTDI port for a serial connection.

The Adafruit Pro Trinket development kit is the bigger, more powerful sister of the Trinket (RS 124-5509, 124-5506) with roughly 4 times the performance and GPIO.


Due to its small size, you cannot stack an Arduino shield directly on top of the Pro Trinket.

What's on Board?

- Micro-B USB connector for simple connectivity to a PC
- Power with either USB or external output(such as a battery)- it will automatically switch over
- Headers for an FTDI port for reprogramming
- On-board green power LED and red pin #13 LED GPIO pins (18 pins)
- 16MHz clock rate, 28K FLASH available
- Reset button for entering the bootloader or restarting the program.
- I2C/SPI Interface for simple hardware integration
- 3 or 5V Output an onboard regulator provides 3.3V or 5V output for powering LEDs, sensors, small motors, etc.
- External reset pin
- 3 Mounting holes

Works with 99% of existing Arduino sketches (anything that doesn't use more than 28K, and doesn't require pins #2 and #7)

The Pro Trinket is available in two versions:

Pro Trinket 3.3 V - 12 MHz (RS 124-5511)
Pro Trinket 5 V - 16 MHz (RS 124-5507)
