Equipped with high-current relay 7250VAC@10A / 30VDC@10A
It can control both AC and DC appliances such as Solenoids, Motors, lights, fans, etc
Trigger current: 5mA
Working voltage: 5V
Module size: 50 x 26 x 18.5mm (L x W x H)
Four mounting bolts holes, diameter 3.1mm
Screw terminals (Terminal Block) provided (C, NC , NO) for quick and easy connection
Flyback diode to protect your microcontroller
Input Signal Pin connected to Burg stick for easy accessibility
LED Status indicators to indicate the relay ON/OFF status.
This single channel Relay Module operates at 5V TTL signal and is perfect for common Arduino/Raspberry Pi control applications.
This board has one (1) on-board relay which can switch up to 10Amps. Relays terminals (COMMON, Normally Closed [NC], Normally Open [NO]) are accessible through screw terminals which makes wiring up the board very easy. The relay is safely driven by transistor BC547 hence your input device, such as Arduino, is protected from relay circuit. There is flyback diode which will further protect your microcontroller from relay kick back.
I had used a lots of LoRa module till now, but it's really the best among all of them! the 1262 is a great upgrade in terms of output power and configuration. we can configure the output power, bandwidth, spreading factor and a tons of other things, which are not possible to configure on previous modules. the radiolib library works preety good with it and it also supports rssi and snr like features, which are very crucial when you are seriously researching on antenna or range related works! that's why I eventually like this module more then ebyte LoRas. To me this is the best module in IN8 68MHz, which is completly legal and free to use in India upto 1W! And also thanks to thinkrobotics, I got it in just 1 working day, and your packaging was also too good! Love your service, and keep this modules available on your websight. Your pricing of this module is too good, and I'll buy many of these modules. Thank you!

Team is suppotive and solves all the queries .
The product is good and will surely help me in my project...looking forward for more trades with think robotics.
