Q: what is the maximum power input i can use to power the arduino
Asked by dash_hold _spash on 2018-12-12 09:47:53
peterjazenga some pins are 5v tolerant, applying 5v to other pins will kill the device it's onboard regulator allows you to use 5v sluts to the vin pin but never exceed 3.3v on the 3.3v pins

peterjazenga Arduino IDE meh but it depends on the goal, at software is powerful but also a complete pain to setup any project, for smaller projects, it's fine I'm using it with ADC DMA, complex timer controls and more without issue
Helpful (0)Q: Does this have a funtioning Serial Port? I don't see a serial chip.
Asked by nagas on 2019-09-19 11:54:37
peterjazenga stm32f103 has 3 serial ports, also supports 1 usb device port, can emulate keyboard, mouse and far more best programmed with st-link

Q: is it capable to measure the energy produced by a solar panel?
Asked by oldBen16 on 2020-07-17 05:05:46
peterjazenga NO This is AC only, the current transformer only handles AC, solar panels supply DC The output voltage of Solar panels varies widely depending on time of day, cloud and of course the type of installation but voltages up to 600v on larger arrays are not uncommon, this unit cannot measure those voltages

Q: how can i get rs232 protocall and referance circuit diagram?
Asked by mothc11 on 2021-05-14 09:47:38
peterjazenga eg8010 is the control chip, Google it, as I haven't needed to use serial, I can't be more specific also it's logic level not rs232 voltage levels

Q: is this machine could be use to heating water?
Asked by Rakan111 on 2019-05-15 20:53:16
peterjazenga Pumps do not heat water it is clear from the description details that the pump can handle water up to 100°C so it is suitable for circulating hot water

Q: what is output voltage? is the output analog or digital (pwm). suitable for arduino?
Asked by sneron7 on 2019-01-04 09:29:22
peterjazenga It is analog, it can be used with Arduino, STM32 or ESP32 for example but to measure AC current properly you must have a fundamental understanding of how it works, understand how to put a load resistor on this device, how to create a floating reference potential and do fast ADC You cannot use this device with slow ADC such as the ADS1115 Before using this, google, there are many examples of using this kind of sensor with Arduino and other boards

peterjazenga nope, note the name psram, it is RAM, it cannot store data without power
