An overview of the IPEC board, showing the various connections and options available. The board was designed to be compact, flexible and functional, combined with safe and expandable features.
IPEC, IoT Power Energy Controller and Monitor SDK boards, are in, successfully tested and available for purchase! The first production batch of both IPEC board variants (ESP32E and ESP32UE), have gone through Configuration, Flashing, Bring up, Calibration and Final Testing. All looking good. The development firmware release I hope to complete this week and upload
The below guide shows the Mains and Solar Power Energy Monitor Board options available. With three current models of Power Energy Monitors, three ATM devices (ATM90E26, ATM90E32 and ATM90E36), and two variants of ESP32-WROOM (32E with PCB Antenna and 32UE with U.FL for External Antenna), this guide should assist in selecting the right board for
EPEM follows in the successful development footsteps of the IPEM and IPEC Power Energy Monitoring Boards. EPEM is an Ethernet Power Energy Monitor and Controller. 3 Phase, or 3 x Single Phases, with DAC/PWM/MPWM/MPPT/I2C Expansion Port Outputs. For remote Solar Power Energy installations which have no/limited WiFi coverage, EPEM is an Ethernet based Power Energy Monitor and Controller. *
The below two videos show the IPEC board outputting PWM and DAC voltages, which are directly controlled via the IPEC ATM90E32 and CT Clamp Input. A current clamp is connected to a variable ramping mains AC load and this is then used to test the IPEC board, which is automatically outputting to the DAC and
Both the IPEC and IPEX BETA boards have been undergoing initial bring up and beta testing – which is going very well and all positive for the first test release. Development firmware has also evolved to supporting the ADC, DAC and PWM Outputs. This is the biggest amount of time has been spent on bring-up.
A range of enhancements have been made to the original Bring-Up Test Code – it is now a full application. The latest updates include a range of improvements, Web Server, Push OTA, OLED Support, Increased Serial Monitor Information and a couple Buglet fixes. Although the development code was originally intended for board bring-up and testing,
The IPEM ESP32UE ATM90E32 IoT Power Energy Monitor – with External U.FL Connector and Antenna – Now is stock.
Based on the ESP32 (with PCB Antenna), and ATM90E32, the IPEM boards are now in stock. Due to the amount of interest, the next production is already in progress . These will include both options of ESP32 (with PCB Antenna and with External antenna).
Update 4th March 2023 The schematic has been updated to 1.2303-201, to allow the option for the CT4 input on both ATM90E32 and ATM90E36 variants to optionally use the ESP32 ADC. This providing 4 single phase, or 3 phase + 1 single phase, monitoring from a single board. Awaiting delivery of the first batch of
