Introduction

SensEdu is equipped with x2 AD8222 Instrumentation Amplifier (datasheet).

Each Amplifier is dual-channel, so we have 4 channels in total. All channels are accessible from the following Jumpers:

• J9: 1st Channel of U5 -> outputs MIC5 - A0 - ADC12_INP4
• J11: 2nd Channel of U5 -> outputs MIC6 - A2 - ADC12_INP9
• J12: 1st Channel of U6 -> outputs MIC7 - A11 - ADC12_INP0
• J20: 2nd Channel of U6 -> outputs MIC8 - A7 - ADC1_INP16

Refer to the ADC mapping table for better understanding.
