Cheap, capable, and built to last.

The STARLIGHT Flight Computer is a simple dual-deployment solution for model rocketry. With a width of 40mm, STARLIGHT can fit in many low-power rockets, and almost every medium and high-power rocket airframe.

The board boasts an 6-DOF accelerometer and two pyro channels, as well as two servo ports!

Just as versatile as ever.

Whether you're looking to build a thrust vectored model rocket or employ the use of dual deployment for your medium or high-power rocket, STARLIGHT has you covered.

Want to connect more sensors or peripherals to your STARLIGHT board? No sweat! This board also comes equipped with eight GPIO outputs, including a SPI bus, an I2C bus, and a UART bus! Two of the eight GPIO are 5-volt GPIO, so you can also interface this 3.3V device with 5V logic!

With tons of online documentation, launching your rocket with STARLIGHT will be a breeze! If you're looking to level up your model rocketry game, STARLIGHT is a great place to start.
