The P4 doesn't have a built-in radio though, so if you want those beefy RISC-V cores you will need to integrate a second ESP32 just to handle WiFi/BT :(
It will have USB-OTG and an LCD driver at least, which so far have been missing from all of their RISC-V parts.
- ComputerGuru 3y agoCost optimization aside, that has always been the best way to use an ESP chip. Just go with one of their barebone models wired up as a peripheral to an ARM or RISC mcu.
- clbrmbr 3y agoYet it’s possible to build some incredible applications on top of just ESP32, especially with extra RAM.
- devmunchies 3y agoWe use esp32-s3 at my company (smart speaker) but we don't don anything fancy. Can you explain this? Why use esp as a peripheral if you already have an ARM chip? We were considering moving off of esp to something that would make it easier do cpu-bound AI inference on-device or to enable more advanced audio DSP algos.
- throwup238 3y agoBased on cost and development time, it’s usually just easier to add an ESP and communicate to it using a generic SPI library or something than to add a radio to your PCB and get vendor libraries working on an arbitrary platform.
- timschmidt 3y agoSeems likely they'll continue releasing more models, further integrating the features of the P4 and C6 for example. Maybe we'll even get some risc-v SIMD instructions and support for off-chip SRAM.
- antoniuschan99 3y agoI think that’s totally fine. Might actually be the future direction. But yea would’ve been nice to have wifi/bt integrated. Eg if you want 5ghz then use c5, or if you want some wifi-6 so c6, etc. Also here’s a talk by them on how to use esp as a wifi coprocessor https://youtu.be/g14aEjnjRLw?si=TgkEyJJ2_L_Shuom https://youtu.be/g14aEjnjRLw?si=TgkEyJJ2_L_Shuom There’s also adafruit airlift https://www.adafruit.com/product/4201 https://www.adafruit.com/product/4201
- Aurornis 3y ago> I think that’s totally fine. Might actually be the future direction. Using a second board just for WiFi is definitely not totally fine for most applications. Having everything integrated into a single package important for everything from reducing BOM count to lower power consumption to development simplicity.
- yau8edq12i 3y agoWithout the builtin radio it's really hard to justify the use of an ESP32 over, say, an STM32. The integrated small package with "everything" to make a fun project is the whole appeal.
- AlotOfReading 3y agoEspressif has a huge advantage in lead times over ST recently. I migrated a few projects over because ST couldn't or wouldn't give us supply in under a month when you could buy ESP chips and have them on your doorstep practically overnight.
- vbezhenar 3y agoDid you look at chinese STM clones? We used gd32, I liked it.
- 6SixTy 3y agoWide product range. ARM and RISC-V all called GD32 with an extra letter for the exact line.
- makapuf 3y agoDepends if you want to condone IP theft (compatible independent developments is of course different but I'm not sure this is the case). R&D, Support, good documentation in English and accuracy of specs come at a price.
- pantalaimon 3y agoIs implementing the same peripheral register API really IP theft?
- makapuf 3y agoNo, this was my remark about being compatible.
- sitkack 3y agoThe ESP8684H2 is 1.20 qty 1, more than enough to handle BT an Wifi, then you can use any MCU you want as your application processor.
