  R102 Bongo Microcontroller

Low cost embedded controller 8 Opto-Isolated Inputs + 8 Relay Outputs


R102 Bongo MicrocontrollerWe are sorry that at this moment we can not guarantee further supply of this R102 controller. The R102 Bongo Microcontroller is a compact, high-performance, low-cost embedded controller built around the Cygnal™ 8051 system-on-chip processor. This C-programmable high-speed microcontroller features opto-isolated digital inputs, 8 high power relay outputs, and serial port capability all in a small footprint.

The R102 Bongo's design enables ease of use and versatile integration into any field or OEM application.

The standard Bongo is the perfect choice for demanding field applications requiring a high degree of digital interface isolation. A serial expansion port is available for additional I/O and communications. This board is an ideal expansion board for other control systems. 

Sample programs with the Keil C compiler are supplied.
