Inertial Aerosystems is introducing a range of low-cost pin-out and demo boards for its small magnetic sensors. Manufactured by USA-based Honeywell Aerospace, these products are designed to facilitate easy evaluation or prototyping at the design stage.
The primary models/kits in this range include:
- HMC1041Z-eval has the single-axis sensor placed on a compact circuit board and pinned to a narrow eight-pin DIP pattern. It removes the effort of hot air reflowing this LCC component to a prototype circuit board and brings out the interface pins for usage.
- HMC1042L - HMC1041Z demo. This demo creates a three-axis magnetic sensing prototype with support analogue circuitry. Board includes HMC1041Z and HMC1042L, three amplifier circuits, set/reset strap driver circuit. Included are five HMC1041Z and five HMC1042L samples.
- HMC6042 - HMC1041Z demo. This demo for the two-axis plus ASIC HMC6042 and the single-axis HMC1041Z provides the sensors and supporting circuitry for three-axis magnetic sensing prototypes. Included are five HMC6042 and five HMC1041Z samples.
- HMC1043 demo. This demo creates a three-axis magnetic sensing prototype with support analogue circuitry. The board includes HMC1043, three amplifier circuits, and set/reset strap driver circuit. Included are five HMC1043 samples.
- HMC5843 demo and 5843-eval. This demonstration board for the three-axis compass provides the HMC5843 plus serial bus communications circuits to convert the 12C data to USB interfacing for personal computers. Includes a 6ft USB cable, software, user manual and five samples of the HMC5843. The 5843–eval is the same part on a pinout board for ease of prototyping.
- HMC6343-Demo for the three-axis compass provides the same facilities as the HMC5843-Demo but with the addition of Windows software.
- HMC6352-demo and HMC6353-eval. The demonstration board for the two-axis compass includes a D9 male serial port for RS232 interfacing together with an I2C to RS232 converter, software and 6ft RS232 cable and power supply. The HMC6352-eval is mounted on a wide 24-pin format (EEPROM) for ease of prototyping on solderless breadboards. Only four pins are used for power and I2C transfer.
All the magnetic sensors use the established Anisotropic Magnetoresistive (AWR) technology, which has the advantage of being sensitive to low fields and having low hysteresis.
