One option is Particle (f.k.a. Spark) Photon - STM32F205 ARM Cortex M3 microcontroller with Broadcom BCM43362 Wi-Fi module, 1MB flash, 128KB RAM for $19. Second option is WiFiMCU - STM32F411CE ARM Cortex M4 microcontroller with Broadcom Wi-Fi module, 2MB SPI flash, 512KB on-chip flash, 128KB RAM for $10. Another option is a much cheaper NodeMCU - ESP8266 ...

I would recommend the Arduino. Arduino chips are absolutely the way to go! The Arduino MEGA uses the ATmega16U2 chip and meets all of your requirements. It can easily run on USB power or less. Features • High Performance, Low Power AVR® 8-Bit Microcontroller • Advanced RISC Architecture – 125 Powerful Instructions – Most Single Clock Cycle Execution – 32 ...

An ATmega328 has three timers, one of which, Timer1, is a 16 bit timer. The Arduino Uno and Nano both use an ATmega328. As you say that you have a A4988 module, then an Arduino Uno with a CNC driver shield would be a simple option: A smaller option would be an Arduino Nano with a CNC board: You could power it via a LiPo, using a TP4056 module, which has ...

It is not clear if you are looking for a microcontroller (i.e. a chip) with wifi support, or a single-board microcomputer with built-in wifi. If it is latter, then you have plenty of options. One of them is the latest iteration of the Raspberry Pi series of single-board systems: The Raspberry Pi Zero W is available for $10. It contains on-board 802.11n ...

There are a number of binary clock designs on Instructables, as well as a few binary watch models. Due to a sign-on requirement for searches, the above link now goes only to Instructables. Use "binary watch" in the search box for the same results, or go to the instructable with this result: One great aspect of Instructables is that you can begin ...

I would personally go for ESP32. With WiFi & BT for US $4 to 5. Here is one for less than $3, including P & P. If you can afford $30, then you can get 2 @ ESP32 LoRo boards, where LoRa means Long Range and is about 15km, line of sight. That is just the first pair I found; I am sure that I bought a pair more cheaply. Those may cost more because then ...

I don't know how to tell what is inexpensive for you. There are lots of options for microcontrollers, for examples this list on Wikipedia. There are options from TI there if you wanted to stick with that, something like the MSP432 might work for you. Otherwise STM32 are ARM Cortex and are inexpensive from China and I assume you can get them easily enough. ...

In Make magazine, Vol. 49 March 2016, they mention the C.H.I.P, this is a $9 single board computer, though it is not yet shipping, and is scheduled to start shipping November 2016. There is also the Adafruit Trinket - Mini Microcontroller - 5V Logic $6.95. Full details listen at linked site. Information on page does state to use the 3V version if you ...

Yes, I was looking for the same requirement last month, I found e-con Systems who make cameras for NVIDIA Jetson TX1. They have a 360degree solution for TX1. I can see that they run 6 MIPI CSI-2 Cameras simultaneously. Please refer : https://www.e-consystems.com/blog/camera/?p=1709

There are microcomputers I suggested in another similar question, and unless your cam needs a specific connector you can choose from those: UP Core - https://up-shop.org/up-core/271-up-core.html 1-4 GB RAM, 16-64 GB eMMC storage, Intel Atom X5 Z8350, 99$USD for cheapest options ASUS Computer Stick VivoStick - https://www.newegg.com/Product/Product.aspx?...

Not Bluetooth, but wifi, therefore it qualifies for "other wireless technology, the "aiball" camera comes in as a candidate. Available on Amazon, as well as a few other locations, it doesn't come in with high praises via the reviews. Here's the better part of this answer. Once you visit the Amazon link, you see other small wireless cameras that may give you ...

Ended up going with setup 1 and using this RFID-reader from Sparkfun. https://www.sparkfun.com/products/14066 I interface the reader by use of the Mercury library in a Python program. Super reliable reader I can highly recommend.

The Arduino is probably one of the best options out there. Another board that you might find interesting is the SimpleLink Wi-FI CC3200 Launchpad. You can program the board via two ways, which are Code Composer Studio (CCS) by TI and Energia (which is basically an Arduino IDE fork). There is a MOD version of this board, but the only major difference is that ...
