BL1800 Single-Board Computer
Models BL1800, BL1810, BL1820
Description
The BL1800 is Rabbit's most compact and lowest cost C-programmable single-board computer. The BL1800 is the perfect solution for applications that have significant cost and size constraints but need a dependable SBC. Fast number crunching is provided by a Rabbit® 2000 microprocessor operating at up to 29.5 MHz.
Features
- Our lowest cost SBC
- Compact 3.5" x 2.5" size
- 4 serial ports
- Fast clock up to 29.5 MHz
- Multifunctional I/O
Measuring just 3.5" x 2.5" (89 mm x 64 mm), the BL1800 provides 24 CMOS-compatible I/O, 3 analog channels, and 4 high-power outputs. Three of the high-power outputs can sink up to 1 amp each and are protected for direct driving of inductive loads.
Two RS-232 ports and 1 RS-485 port support serial communication and are rated at 15 kV for ESD protection. The fourth serial port is a 5 V CMOS-compatible programming port that can also be used in the user's application after programming is completed.
Five 8-bit timers and one 10-bit timer with 2 match registers are onboard. Four of the 8-bit timers can be cascaded from the first timer. A real-time clock (RTC) provides time/date data, and a watchdog supervisor is standard.
The BL1800 features a switching regulator that provides a wide range of input voltages (8–40 V DC), reducing power consumption while minimizing heat. (A linear regulator is featured on the BL1810 and BL1820 versions.)
Programming the BL1800 Single-Board Computer
Programs are developed using Rabbit's industry-proven Dynamic C® software development system. An extensive library of drivers and sample programs is provided.
