+## R2 Version Update:
19
+- Main image is the R2 version.
20
+- Default use capacitive dropper method as non-isolation AC-DC power supply, supply current up to 100mA. Add fuse and varistor general protection.
21
+- Previous ACDC power supply method MP150 is still also available, current supply up to 200mA, further improve reliablility.
22
+- HLW8032 energy measurement on board one side, and ACDC power supply on other side
23
+- Add ACDC power supply LED indicator.
24
+- Add jumper between ACDC power supply and supply for HLW8032. You can test HLW8032 with your lab power via jumper pin header.
25
+- We may soldered the cables for testing purposes, you can remove them later or add notes to ask us to do so.

8
+- The HLW8032 is a high precision energy metering IC that uses a CMOS manufacturing process and is primarily intended for single phase applications. It can measure line voltage and current, and can calculate active power, apparent power and power factor.
9
+- The device integrates two ∑-Δ ADCs and a high-precision energy metering core. The HLW8032 can communicate data through the UART port. The HLW8032 uses a 5V supply, a built-in 3.579M crystal, and an 8PIN SOP package.
10
+- The HLW8032 has the advantages of high precision, low power consumption, high reliability and strong adaptability to the environment. It is suitable for energy metering of single-phase two-wire power users.
