Hi everyone there!! Can anyone give a tutorial about how to chose brushless motors propeller (sire and shape), thank you
MYou should look for guides on brushless motor selection based on factors like KV rating (speed) and motor size (torque).
Also Research propeller selection based on diameter, pitch (thrust vs. speed), and number of blades.

Choosing the right combination of motors and propellers for your quadcopter is a critical step in optimizing its performance. This guide…
AThis is the first time I see this site, looks interesting 
MFor real 
AYes 
MIts been very resourceful, my tool in the long run .
ALooks like it will be for me too, thank you again
MSo i started using Zephyr RTOS , any idea on some amazing solutions or projects I could implement with this ?

CThanks, the converter has a current of 1A and operates at the range of 500KHz any good choice on this. You can send a link if any. Thanks

MHi all, How to select Half bridge driver
T@Joseph Ogbonna @ShreeshaN @Petr Dvořák @pallavaggarwal may have some advice but this is also a great question for @Navadeep during OH later today—especially with respect to how you can effectively source whatever you select: general-dev-chat
TAlso helpful if you can provide some context around the application/use case/system design
MWe want 24V 7A BDC control circuit
PEach renowned manufacturer provides engineers with application notes, reference designs and design guides. I believe the best start is to study available literature before.
WHi guys. Anyone here could help to identify this part.. it's part of DSP preamp board...
LThe one and only @techielew leading the panel conversation during the IoT Stars meeting. It was great meeting you in person!
JAwesome 
NBig shot Brandon! This is awesome @techielew

CWow! Brandon ! We are so proud of you 
@techielew
@techielewCHello everyone! I have a question 
CI would like to send values from an Arduino to another one (one value every 10 minutes). I have a distance of 80-100m outdoors with trees between the Arduinos. The transmitter should consume as little power as possible because it will be on battery, while the receiver will be on mains power.
What solution do you suggest? I don’t know the maximum distance (WiFi, radio, Bluetooth, IR…).
Thanks

Thanks
JYou can use a simple Lora Device if you are not sure of the distance. It acts as a radio transmitter and covers a large area
Whi camila , recommend using LoRa (Long Range) technology, for long-range, low-power wireless communication , you'll need a LoRa transceiver module compatible with Arduino, such as the RFM95W or SX1276/77/78/79 module
IAnother option is Bluetooth with Coded PHY support. This extends the range of bluetooth and is likely the lowest cost and power. LoRa is a good option as well, but your receiver has to function as a gateway. LoRa will have the best range, but BT coded PHY should meet or exceed your range needs as well. As always with wireless range, I would do some field testing with existing product or dev kits before finalizing your design. Also, antenna design/performance is always a large factor with any wireless design.
T@PCB & Analog and @MCU, MPU & Firmware, should be another hot one from @Navadeep!
NStarting in just about 2 mins. See ya'll there!
COk, thank you! I got it!
CYeah thanks Wafa actually I was wondering about the option of nrf24l01 + pa + lna? Does it consume more power
COkk thank you Mike I’m curious, have you encountered any specific challenges or drawbacks when compared to LoRa? I’m always interested in learning from others.
