Nice sensor. In some application can replace a PIR sensor.

Great device. Had it for two years, still going strong. My comment is that the GPIOs 4 and 5 are mislabeled on the board AND the reference photograph GPIO4 is GPIO5 and vice-versa

Hi, Thanks for bringing up the questions. According to the databook, 1. The LGT328P has 32KB flash, 2KB SRAM, but configurable EEPROM(shared with flash) 2. It does not have independent EEPROM port from the flash, it can be set to simulate as shared EEPROM from flash. This probably need a initialization method, which is not same to standard arduino libarry. 3. There is a method called "LPM" command to read the data structure. 4. We are poor at code, we update a C demo code from EEPROM LGT328P in the git, please see here. https://github.com/Edragon/LGT/tree/master/1-LGT8F328/Demo%20Code/lgt8f328p_eepp Please also take look into the datasheet. Thank you. Best regards,

Using the LGT8F328P as an Arduino Nano replacement. Am not able to get the EEPROM.h library to work. What is saved and what is read back from the same eprom memory address does not tie up. The reading error is also random. Sometimes one address will work 100% and then other times is's a complete failure. PWM and AI (12bit) seems to work correctly. Gryskop.

this module is very sensitive to DC power noise. using an AC offline DC switching module to convert 120VAC to 5V with ESP8266 module, this module will constantly false trigger. I helps to use pi filter with 10mH and two 470uF, then filter false triggers in software. They are handy, but beware of glitches.

Good range compared to other modules. Does require good quality power supply to reach its advertised 40cm though (the video in the description was run on 3xAA/AAA type batteries!) but even on a "normal" supply you will get ~20cm. I don't know the exact range I get out of the cheap rdm6300 modules under comparable circumstances with the same card but it might be as short as ~2cm. So thumbs up for this module. Was also able to run it on 3.3V ... range seems to be the same as on 5V (at least with a crap power supply).

Hi Jaggit, From our test, either 3.3V or 5V the module can work, but the on board ACDC supply 5V out.

Please, those people who report that the module works correctly, can you inform us of the voltage Vcc that pins 1 and 5 have? (HLW8032 supply voltage) Thank you

arrived on time, also the second smallest form factor i could find on the market! pity very hard to find a suitably sized edge connector.

Good solid product. You have to read the wiki page for the connections and use github code in the beginning. Support from the store is excellent. I achieved around 30cm with the included fat card. Buzzer is not included.

Nice cheap module. You have to know that this module must be positive center powered and there is no reverse polarity protection.
