ESP32-S31

How do I order a few samples, seem like there is a MOQ ?

Also I want to dive into hardware stuff but I'm always clueless as to what I do afterwards when this would arrive? Are you using a generic board or are you ordering and designing PCBs to hook this up to?

What are you using it for ? How do I go from a prototype to mass production via kickstarter?

This looks like the long-awaited replacement for the original ESP32. The S and C series have been relatively low performance (the S better than the C but stuck on the outgoing Xtensa architecture), the P4 is powerful but lacks wireless. This is a relatively high performance, dual core MCU with wireless; a nice default option for low volume designs where being able to copy a previous implementation is more important than saving a few cents. Just like the ESP32. Nice.

Espressif is on fire! And the CPU even has SIMD instructions!

RISC-V cores is a big deal for embedded systems because now compiling for SoCs is only a matter of `rustup target add riscv32imac-unknown-none-elf` instead of downloading half-broken proprietary toolchains and SDKs.

Take a look at https://kerkour.com/introduction-to-embedded-development-wit... and https://kerkour.com/rust-esp32-pentest to get started with modern (Rust ;) embedded development.

The specs look great, will see how long it takes to get these as WROOM modules or on little dev boards; my two form factors of choice for Espressif devices. I'm also curious about the pricing, so far they've impressed me with how much more you get in successive generations at a similar price.

If you're excited about the (relatively) speedy RISC-V cores and SIMD, look at the P4 which is available now. It has a slightly faster clock but no wireless: https://products.espressif.com/#/product-comparison?names=ES...

There's some cool work out there using the dsp functionality and built in image handling to crunch a lot of pixel data, which should work similarly on the S31: https://www.reddit.com/r/WLED/comments/1ry2jd7/wledmmp4_with...

It being RISC-V is awesome, but how does it make sense that it's S series when S series have been Xtensa cores? Why is it not C series?

Good to have WiFi and wired ethernet on the same part again.

Although we lost the MIPI support that the P4 dual-core RISC-V line has.

Any reason why this device wouldn't have Z-Wave? Is the wireless protocol significantly different than Thread and Zigbee?

I've been building hobby LED art projects with WLED (exclusively built on the ESP32 platform). It's been a blast. These little boards are so powerful and the open source community continues to amaze me.

My preferred controller platform is of the QuinLED line - comes with power distribution, voltage regulators, fat copper lines, configurable data-line resistors, and smart auxiliary hardware support all for an affordable $30-$50 per controller. (quinled.info)

I'm interested in audio out because I dabble in musical instruments.

What's the state of Bluetooth audio out on microcontrollers? Is low latency and high quality output possible?

This looks like a nucleo144, except its risc-v... but why would I use it over said nucleo144?

When can we buy these?

Love to see more RISC-V in the wild

The 1GB bandwidth is interesting. It also has Simd instructions too.

Could this theoretically be used as a router or wireguard vpn instance?
