![]() ![]() A new red LED near the USB connector gives you some status information, while the traditional “Arduino LED” is orange. There’s the usual dual row of pin headers you can plug into a breadboard, a micro-USB connector, and reset button. The board looks superficially similar to the older 3.2, at least from the top. The board launches today, but I had a chance to test drive a couple of them in one of the East Coast Hackaday labs over the past few days. And it rings up at an MSRP of just $19.95 a welcomed price point, but not unexpected for a microcontroller breakout board. ![]() Programming? Easy: there’s an add-on to the Arduino IDE called Teensyduino that “just works”. Of course, the new board is also packed with periperals, including two 480 Mbps USB ports, 3 digital audio interfaces, 3 CAN busses, and multiple SPI/I2C/serial interfaces backed with integrated FIFOs. The latest in the Teensy microcontroller development board line, the 4.0 returns to the smaller form-factor last seen with the 3.2, as opposed to the larger 3.5 and 3.6 boards.ĭon’t let the smaller size fool you the 4.0 is based on an ARM Cortex M7 running at 600 MHz (!), the fastest microcontroller you can get in 2019, and testing on real-world examples shows it executing code more than five times faster than the Teensy 3.6, and fifteen times faster than the Teensy 3.2. After visiting the expo, we saw that all the designs from the participant companies used one of the first two, and no one was willing to commit to the SK Hynix NAND at this point.Paul Stoffregen did it again: the Teensy 4.0 has been released. This Phison E16 controller uses either Toshiba NAND flash, Micron NAND flash, or SK Hynix NAND flash. It also uses the Phison E16 controller and this is the most important aspect. It is using the host interface of PCIe Gen 4 x 4. ![]() However, the Essencore drive which is displayed at the show has one feature which none of the other drives has. It is not hard to see that some of the companies are glad to go with the turn-key solution for entering the market as soon as possible, while others just want to sit back and tweak the firmware for better performance in the feature, but they will release their products later. However, it still depends on which company you ask. The expo shows that at present, only the drives which are powered by Phison’s E16 controller might be ready for mass market. ![]() This year, one of the underlying themes was the number of PCIe 4.0 SSDs on the display.
