This board costs about the same as an Arduino Uno and less than an Arduino Mega, but it offers significantly higher performance than both boards. The thing that makes this board so powerful is <strong>RT1602, a crossover MCU based on a 600MHz ARM Cortex M7 32-bit processor. </strong></p><div id="ezoic-pub-ad-placeholder-656" data-inserter-version="2" data-placement-location="under_page_title"></div><script data-ezoic="1" data-no-optimize="1" data-no-defer="1">ezstandalone.cmd.push(function () { ezstandalone.showAds(656); });</script><p class="wp-block-paragraph">The Board comes with 1024 KB ram, 7936 KB flash memory, and 4KB EEPROM. There are <strong>18 analog pins and 55 digital I/O pins </strong>on board out of which <strong>35 pins support pulse width modulation.</strong> This board supports <strong>CAN, I2C, and SPI serial communication protocols</strong>.</p><p class="wp-block-paragraph">If we compare this board with the Teensy 4.0, we can find Teensy 4.1 includes <strong>an Ethernet controller </strong>and<strong> an Ethernet PHY chip. </strong>Only an RJ45 mag jack kit is required to connect an Ethernet cable.
