uM-FPU64 Breakout Board




$2.99 ea.

The uM-FPU64 28-pin breakout board provides for convenient mounting and access to all uM-FPU64 pins.

Description [Hide]

The uM-FPU64 is a floating point coprocessor has the speed and features required to support today's advanced microcontroller applications. Software math libraries often use large amounts of memory on microcontrollers, particularly as more complex library functions are used. The uM-FPU V3.1 chip offloads this overhead, and provides a comprehensive set of floating point operations, including advanced functions such as FFT, matrix operations and NMEA sentence parsing. The breakout board provides support for SPI and I2C connections, breakout connectors and other options. A serial programming/debugging connector is also available which is compatible with the SparkFun FDTI Basic Breakout - 3.3V, Solarbotics TTLy-FTDI (in 3.3V mode) and Parallax Prop Plug USB to serial adapter.


  • All required connections for the uM-FPU64 (not included)
  • Interface selector for SPI or I2C
  • Serial connector for access to SERIN and SEROUT pins
  • Power or Busy Status LED
  • Space for Real Time Clock (RTC) crystal and caps
  • Breakout connectors for D0-D4, D5-D8, & A0-A5
  • Optional pull-up Resistors for D0 and D1
  • Board can be power via USB during development
