Talk:ESP32

InfoBox: Successor

Should the ESP-32-S2 link to the section on this page discussing it? Or is it notable enough for its own article? SerahTheLioness (talk) 17:29, 7 March 2021 (UTC)

The ESP32 has a Xtensa LX6 core, the ESP32-S2 and ESP32-S3 have LX7 cores. No much difference. More difference have ESP32-C3 and ESP32-C6 with RISC-V cores. But the "family signature" is on-chip Wifi and Bluetooth radio and how program memory is copied from flash to internal program memory (cache). Keep the ESP32s together.

ESP32 RAM

The useable RAM for data is 160 KByte static RAM and 160 KByte heap RAM. See https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/mem_alloc.html#available-heap AndreAdrian (talk) 17:21, 20 July 2021 (UTC)

ESP32-H4

The H4 was announced in April 2024, but as of January 2026, no actual hardware has been released and the SDK has no support for it. @Rkarlsba has added specifications from the press release, but no official data sheet seems to exist. Unless there are strong reasons to leave it in, I'm going to remove it for now. It can be added back when a launch happens. Thoughts? MadScientist (talk) 01:56, 21 January 2026 (UTC)

The only reference to the H4 I have found is the high-temperature variant of the ESP32-WROOM-32E/UE, but this is not based on the ESP32-H4. It uses the original ESP32. If there is no further comment, I will remove it in a few days. MadScientist (talk) 03:32, 28 January 2026 (UTC) MadScientist (talk) 03:32, 28 January 2026 (UTC)

No other comments in 2 weeks. I am removing it. If there is ever a release, we can put it back, MadScientist (talk) 15:04, 4 February 2026 (UTC)

Too much tables

this article just looks bad due to how much tables are used. It's a pain to read. All of the tables should be moved to a dedicated "parameters" section or something. Mruwkarz (talk) 16:05, 14 March 2026 (UTC)
