Can i solder two 0.5W Solar Panels 55x70 together on one socket so i would have 1W of solar input?
Hi, v2.0 is not available now, it will be released one month later.
yes you can, but add a diode to each panel if it possible.
It's work well this Solar Charger Shield V2 with a system that have 20 modules Solar Panel 80X100 (1W)? Thank you
Hi Yesenia.I'm sorry that we have no experience of using GPRS and decoder with phone.
Hi, there are no need to add 20 solar panels to solar charger shield. One or two modules at most.
Could you guys please tell me what the difference is between this Solar charger shield v2, the energy shield, and the lipo rider? Like why would I buy the Energy shield over this solar charger shield v2? I know there are some subtle differences between
Hi Dave Dugan.I'm sorry that the GPRS shield can't send a SMS test with an emial address as a recipient instead of a number.
Hi, I have just received the Shield from my local supplier and I am using it on robot, based on Arduino Mega. My question is if the power is supplied via 5v pin to arduino? I am guessing That it is not VIN as 5v is to small for the regulator. Is it saf
Hello, its rivision of 1137B11SIM900M64_ST, version B11.
The low voltage of a drained battery seems to cause excessive current draw, preventing it from charging from a solar panel while powering other circuits.
There needs to be some sort of automatic load switching to prevent the circuit from draining
wow~Positive solutions upstairs.
I'm experiencing the same problem, if you ever find a solution please share it!
Many thanks in advance...
Hi, using a 6V 2W solar panel, sunny day, 1mA 3,7 Li-ion battery, and still the Vin pin never goes higher than 1.36 Volt. According to the wiki it should reach 2V in order to start charging the battery. What is wrong? Many thanks in advance
Hi, when can we order GPRS 2.0?
Maybe you need more intense sunshine,i think.
What is the maximum acceptable input voltage and current from a solar cell?
ok, but I could not run ... smsread incoming
Thanks. What would happen if the voltage were to exceed this value? e.g. using a 7V solar cell. Is there over voltage protection/regulation?
Can this stack ontop of the Arduino Mega 2560, and still allow other boards to stack ontop of it?
Yes, it is. Sorry that we get the chip with official firmware and we do not know how to customized the firmware. You could refer to At command documentation, there is AT command for controlling the GPIO.
Hi,you can plug solar shield into our other products(shields,seeeduino,etc),and you can use mega with solar shield,but there are some differences between Arduino and Arduino Mega,such as attachInterrupt,more informations you can refer to this website:<
What is the switch used for? I don't see it listed in the schematic. Can the board function as a UPS, and automatically charge when solar power available, and switch over to battery/usb otherwise? Or do you have to manually switch from one to the other
Hi.You can switch the working mode of Energy Shield between “OFF” and “ON” via the working mode select switch. In “OFF” condition, Lipo battery doesn’t output but only pull current from any existing power source. In “ON” condition, the battery gets cha
