The open-source Arduino Zero compatible board – called Tachyon – features a 32-bit ARM M4F processor running at 120 MHz, and has 128K of RAM. According to its developer, the Tachyon’s pinout is nearly identical to both the Neutrino and Arduino Zero, making it a drop-in replacement for virtually any project using either one.
Key specifications include the following:
- Microcontroller: Microchip ATSAMD51G18A ARM Cortex M4F
- Clock speed: 120 MHz
- Operating voltage: 3.3V
- I/O pin limits: 3.3V, 7 mA
- Digital I/O pins: 14 w/ 12 PWM
- Analog input pins: six 12-bit ADC channels
- Analog output pins: two 10-bit DACs
- Flash memory: 256 KB
- SRAM: 128 KB
- Voltage regulator: 3.7-5.5V input / 3.3V, 300mA output
- Dimensions: 1.4 x 0.7″ (36mm x 18mm)
The Tachyon features a red status LED that users can control in their program. In addition, a green LED indicates when the board is receiving power.
The Tachyon is programmed via a PC using a micro USB cable, and ships with the Zero bootloader installed. Once the campaign is completed, the developer will provide users with the relevant Eagle CAD files and schematics, which can be freely modified and integrated into users’ own designs, with no payment of royalties or licensing fees.
The crowdfunding campaign ends on August 29. Its funding goal of $5,000 has already been exceeded, with 14 days remaining. For more, see the Tachyon Kickstarter campaign page.
