Espressif's ESP32-C5 Is Now in Mass Production

Announced 2+ years ago (almost 3, now that I look: <a href="https:&#x2F;&#x2F;www.espressif.com&#x2F;en&#x2F;news&#x2F;ESP32-C5" rel="nofollow">https:&#x2F;&#x2F;www.espressif.com&#x2F;en&#x2F;news&#x2F;ESP32-C5</a> ) and sampling 1+ year ago, good to see it finally come. 5GHz support is increasingly important.

The big anti-feature is that developers can block users from flashing the chips.<p>Yes, there&#x27;s a security angle, but if I have the chip in my hands, I should be able to flip some pin to reprogram the chip and prevent all the e-waste.

I wonder if the power consumption is any better. An nRF runs circles around any existing ESP32 variants in terms of power.

This is looking pretty great, I&#x27;ve really wanted a MCU with Zigbee on it, for the various little battery-operated devices I&#x27;ve wanted to make. However, with Espressif&#x27;s lineup, I&#x27;ve really lost track of what does what, lately.<p>Does anyone know of a good comparison resource?

This microcontroller, like all microcontrollers Espressif released in the last few years, uses RISC-V as the ISA.

Any guesses as to when a hobbyist might be able to buy the module without the dev board? Their aliexpress store didn&#x27;t have them as far as I can tell, I assume they are prioritizing dev boards for the moment unless you&#x27;re a big enough company to actually talk directly with Espressif.

Let&#x27;s hope they will finally enable the USB Host HID Class Driver to support non-boot protocol devices this go around.

Is the 10k unit price public?

Would an esp32 be the best soc for LoRa? I don&#x27;t need WiFi or BT, which I know I can turn off to save power. Contemplating trying STM32 instead, don&#x27;t have experience programming it yet.

Hopefully p4 will be released soon too!

I wish there was something more powerful than STM32H7 or RT1070 available. It would be awesome to be able to compute complex algorithms in real time.

I wanted a board with Zigbee support but $21 ($16 plus $5 shipping) is quite expensive for a single board.

Too bad after tariffs, this little guy would have cost $10-15 and now will probably be $50 +<p>I feel like the Trump admin is going to have to make a carve out for the esp32 or certain Espressif products. So many IOT businesses going to go out of business if these MCs baloon in price.

Bought a bunch of ESP32-C3 Supermini boards for 1.05€ each. Incredible value.

They link to a $15 developer board on Aliexpress (much the same as the rest of the ESP developer boards floating around for years) which is now inflated to $35 with tax, shipping, and tariff.<p>My impulse purchase has been tempered with &quot;eh, do I really need it?&quot;

Honestly, shipping stuff direct from China and paying more for it here always trips me out, but it&#x27;s kinda the norm now. You think it&#x27;ll get easier to actually repair or reprogram stuff or are we just stuck tossing hardware once it&#x27;s locked down?

$126&#x2F;ea in quantity after tariffs.<p>Why do I have this sickening feeling that in a few years anyone doing anything with hardware is going to be ordering everything direct from China, like we&#x27;re some kind of undeveloped client state?

how much memory does the dev kit have? it’s not clear after following links off that article.

Does it have floating point hardware?<p>Does it have CAN?<p>How does the core compare to their old ones?<p>I&#x27;m a little disappointed that it only has one core even though I haven&#x27;t used the second one on the older chips yet.

If anyone from Espressif seeing this, I love your MCUs. But can you please improve the ESP-IDF so that it&#x27;s usable on BSD systems. The Linuxisms baked into its build system is unnecessary.<p>I think moving from Make in the old version of IDF to CMake was a mistake.

from my understanding RISC-V chips are slower and more expensive and less optimized compilers, so why in the world would an end user use one?
