The PCA9685 is a 16-channel I2C-bus controlled LED controller optimized for Red/Green/Blue/Amber (RGBA) color backlighting applications. Each LED output has individual 12-bit resolution (4096 steps) PWM controller with a fixed frequency. The controller operates at a programmable frequency from a typical 24 Hz to 1526 Hz with a duty cycle that is adjustable from 0% to 100% so the LED can be set to output a specific brightness. All outputs are set to the same PWM frequency. With the PCA9685 as the master chip, the 16-channel 12-bit PWM Servo Driver only needs 2 pins to control 16 servos, thus greatly reducing the occupant I/Os. Moreover, it can be connected to 62 driver boards at most in a cascade way, which means it will be able to control 992 servos in total.
Features:
Contains an I2C-controlled PWM driver with a built-in clock. It means, unlike the TLC5940 family, you do not need to continuously send it signals tying up your microcontroller; it's completely free running!
5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs, which is good when you want to control white or blue LEDs with a 3.4V+ forward voltage
Supports using only two pins to control 16 free-running PWM outputs – you can even chain up 62 breakouts to control up to 992 PWM outputs.
3 pin connectors in 4 groups, so you can plug in 16 servos at one time (Servo plugs are slightly wider than 0.1" so you can only stack 4 adjacent ones on 0.1"-hole female headers.
12-bit resolution for each output - for servos, that means about 4us resolution at an update rate of 60Hz.

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.
