Strange that the page talks about it being for $3 esp32 devices, but the only esp32 devices it can run on are the preflashed ones which are $12. What?

- _fizz_buzz_ 8y agoSeems like that is the chip: https://www2.mouser.com/ProductDetail/Espressif-Systems/ESP32-WROVER?qs=sGAEpiMZZMve4%2fbfQkoj%252bAHtY6NxmdO7OI28pxTaRVM%3d https://www2.mouser.com/ProductDetail/Espressif-Systems/ESP3... Maybe you can flash them yourself somehow.
- jerrysievert 8y agoI wasn't able to find them for $3, but I did find quite a few boards ready to use on AliExpress for $4-5, as long as you're willing to take the 30 day hit on delivery. if you're ordering domestically, you'll find them more the price that you're quoting, with much quicker shipping times.
- magicalhippo 8y agoWas that with the additional 4MB PSRAM module needed for low.js?
- jerrysievert 8y agoyou mean the ESP32-WROVER? $4.50 at AliExpress if you order single. that's the specific version of the esp32 called out on the low.js page, and according to the specs sheet is the version with the 4mb SPI accessible ram, yes. that said, just use jerryscript (no relation), and you can run in 32k.
- ricardobeat 8y agoDuktape also runs in 32k (or less), but this is an implementation of the entire node.js API, not just the engine.
- magicalhippo 8y agoCheapest boards I can find on AliExpress is $7 and up. If you just want the module then yeah $4.5.
- opencl 8y agoThe ESP32 version isn't open source though. It's one of those "open core" commercial projects with the commercial part being selling the dev boards/preflashed modules.
