KMA36R PERIPHERAL MODULE Digital Magnetic Encoder Sensor General Description The KMA36(A) peripheral module provides the necessary hardware to interface the KMA36, A universal magnetic encoder for precise rotational measurement. To any system that utilizes Pmod compatible expansion ports configurable for I2C communication. The KMA36 sensor feature a system-on chip technology that combines a magnetoresistive element along with analog to digital converter and signal processing in a standard small package. This model can operate from 3.0V to3.6V, by using Anisotropic Magneto Resistive(AMR) techonogy, the KMA36 can determine contactlessly the magnetic angle of an external magnet over 360°.

It can plug directly into a Pmod-compatible port (configured for I C) through connector J1, or in this case, other I2C boards can attach to the same I2C bus through connector J2. I2C Interface (Daisy Chaining Modules) 2 Alternatively, the peripheral module can connect to other I C-based Pmod modules through the expansion J2 connector. Connector J1 provides connection of the module to the Pmod host. The pin assignments and functions adhere to the Pmod standard as shown in Table 1. 2 2 The J2 connector allows the module to be connected through a daisy-chain from another I C module and/or provide I C and power 2 connections to other I C modules on the same bus. See Table 2. External Control Signals The IC operates as an I2C slave using the standard 2 wire I2C connection scheme. The IC is controlled either by the host (through the Pmod connector). In cases where one or more of the SCL and SDA signals are driven from an external source, resistors R1, R2 provide pull-up. However, this also increases the apparent load to the external driving source. If the external source is incapable of driving these loads, they should be removed.
