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)ĭue to its small size, you cannot stack an Arduino shield directly on top of the Pro Trinket. 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. 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. If both are connected, it will use whichever has the higher. The circuitry inside will use either the battery or USB power, safely switching from one to the other. This pin can take up 16V DC input, and has reverse-polarity, over-curent and thermal protections. 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. Battery + Input - take your Trinket anywhere and power it from an external battery.
You can also use an FTDI cable to connect to the FTDI port for a serial connection. 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. Uses the Atmel ATmega328P microcontroller, 28K of flash, 2K of RAM and 18 GPIO. The pro trinket features Microchip’s ATtiny85 MCU with 8KB program flash, 20 MIPS CPU, 5 PWMs, 2 8 bit timers. Small form factor means it can easily be incorporated into prototype/ design. The Trinket doesnt have a JST connector on board, so well have to. Most of our lithium polymer batters have JST connectors. To power the Trinket, well use a lithium polymer battery. The Trinket has enough memory to power about 100 NeoPixels. Adafruit Pro Trinket Mini MicrocontrollersĪdafruit 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. The Trinket 5V micro-controller runs code that will animate the NeoPixel Strips and NeoPixel Rings.
