General Info


The Birdbox-A can be used to convert protocols into different formats, for communication among different systems. It offers a complete C/C++ programmable system with a high performance CPU (40 MHz 188), up to 512 KB ROM/Flash, 512 KB battery-backed SRAM, a 512-byte serial EEPROM, ADC, and DAC.

The BB-A also supports a real-time clock (RTC72423), battery, three timer/counters, a watchdog, up to four serial ports, a 16×2 character LCD, and a 3×4 keypad, all of which can be packaged in a 4.8 x 3.7 x 1.5-inch aluminum sheet enclosure.

The four serial ports are RS-232 by default. The two optional UARTs can be configured for RS-485. The counters can count external events, at up to 10 MHz or generate PWM outputs. 32 I/O pins from the Am188ES are multifunctional and user programmable.

The eleven channel 12-bit ADC has sample-and-hold, a high-impedance reference input, and a sample rate of up to 10 kHz. Two optional 12-bit DAC provide 0-4.095V analog voltage outputs capable of sinking or sourcing 5 mA.

Two PPI chips (82C55) provide 24×2 bi-directional I/O lines that support a DB25 parallel printer port, 3×4 keypad, and 16×2 LCD (provided as part of the optional BB-Pack). Seven solenoid drivers can sink up to 350 mA at 50 V per channel.

A special configuration (BB-I) can be driven by the i386-Engine. The original version BirdBox supports only the V25-Engine.


Includes 188 40 MHz with 128 KB SRAM, 32 I/Os, 2 RS-232, 3 timers, watchdog timer, 512 byte EE, 7 solenoid drivers, 2xPPI, watchdog, 5V linear regulator. Does not include add-on options, OEM option discounts available.
