Topic: "Fastest" Arduino compatible board (Read 24357 times) previous topic - next topic

I have created an Arduino board for myself. 480MHz clock speed, 1MB SRAM 2MB FLASH. With some stuff already on board (like 6 servo connectors) STMH7 uC used
Why aren't you using the same microcontroller as the Teensy 4.0?

NXP currently has a special deal on their 500MHz i.MX RT1010 (ARM Cortex M7 "Crossover") evaluation board: https://www.nxp.com/design/development-boards/i.mx-evaluation-and-development-boards/i.mx-rt1010-evaluation-kit:MIMXRT1010-EVK  $10.10 (!!)
They don't mention Arduino IDE support, but they appear to have shield-compatible connectors.  NXP is a multinational company, this may have better shipping options for non-US customers.


I should probably also mention some of the new RISC-V boards that have been appearing, like the $5
Sipeed Longan Nano - RISC-V GD32VF103CBT6 Development Board
From Seeed Studio.
Also no Arduino Support, AFAIK.


I wish I could get more excited about the higher-speed boards.  In theory, they are cheap enough buy "just to try out" (perhaps not cheap enough for volume use?)  In practice, I already have a stack of "faster and more powerful" boards that I haven't done anything with :-(

Pricing for the NXP RT1010 chip is $1.09 @ 10K quantity! The chip does not have on-board Flash so a SPI or QSPI Flash chip is required. Maybe there will be some 500 MHz M7 pill-type boards in the future.

ESP8266 and ESP32 doesn't have on-board flash too it seems that the fastest MCU doesn't have on-board flash.

Flash memory is comparatively slow to access (~50ns); even the moderately slow ARM chips (like the 48MHz SAMD21 on Arduino Zero) require that you configure wait-states for the flash at their top clock rates.  To compensate, vendors add various sorts of "flash acceleration" ranging from extra-wide reads (fetch more than one word at a time) to full-fledged cache memory systems.

Hi, our risc-V board longan nano have arduino port: https://github.com/sipeed/Longduino
and our dual-core 400M risc-V board maix(price from 10$ maix nano) have arduino port too: https://github.com/sipeed/Maixduino
