The module includes a state-of-the-art, high-resolution QMC5883X series magneto-resistive sensor, plus an ASIC containing amplification, automatic degaussing strap drivers, offset cancellation, and a 12-bit ADC that enables 1° to 2° compass heading accuracy. The I2C serial bus allows for easy interface.
The Honeywell QMC5883L is a surface-mount, multi-chip module designed for low-field magnetic sensing with a digital interface for applications such as low cost compassing and magnetometry
The 12-Bit ADC coupled with low noise AMR sensors achieves 5 milli-gauss field resolution in ±8 gauss fields
Low voltage operations and low power consumption; supports built-in self-test
Built-in strap drive circuits, I2C digital interface, wide magnetic field range (+/-8 oe)
Working voltage: 3.3V - 5V
PCB size: 1.3 x 2.3 cm (QMC5883L size: 3.0 x 3.0 x 0.9 mm), with a 16-pin leadless chip carrier (LCC)
The crimper has been received on the 2nd day after placing the order. I was initially sceptical to make payment in advance but proceeded anyway. Unfortunately the dies of SN-28B were deformed. I contacted the team through WhatsApp and they replaced the dies within two days with no extra charge for shipping. The shipping speed is really great. I put the crimper to test, they really made great crimps for my automobile harness. I am great satisfied with the purchase.
The product photos show a group of three pens. One is likely to be misled that one gets three pens for Rs.40/- but one gets only one pen for Rs.40/-. The thing that sucks is that the pen costs Rs. 40/- but shipping costs Rs 90/-. So while ordering this pen, order as many other parts/components you will need to spread out the shipping on a large number of components.
