its rules on Reddit

ESP32 is a series of low cost, low power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. The ESP32 series employs either a Tensilica Xtensa LX6, Xtensa LX7 or a RiscV processor, and both dual-core and single-core variations are available. It includes in-built antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules as well.

Where to post: Normal post about your ESP32 product or project, at most once per quarter, with an explanation of what it is and why

What it requires: One post per product/project per quarter (3 months); explain what you are sharing and why; link source code; stay in the comments and participate; strip referral/tracking parameters from product links; explain the ESP32 engineering angle if cross-posting

What its rules say about promotion

Excessive self-promotion or cross-posting; no media-only links.
Products, projects, etc. are limited to one post per quarter. (3 months) Reddit's rules say this is not an announcement forum for every new release you make. /r/esp32 is a community, not an announcement (spam) host. If you make a post, monitor comments and participate—don't just spam and run. Upvote posts that advance the conversation. If your post is cross-posted to a zillion subreddits, it's probably relevant to none. Explain WHY and HOW this was a unique ESP32 engineering challenge here.

All 7 rules of r/esp32

Search (here and the web) before posting
/r/esp32 has been around for many years, with over 200k participants. Please use the search feature (at the top of the page, to the right of the reddit logo) and see if someone has answered your question before you ask it again. Use https://www.reddit.com/answers and https://chat.espressif.com. Resources like https://randomnerdtutorials.com, https://esp32io.com/, and https://learnesp32.com/ for great intros for all skill levels. Start there if you're a beginner.
Low-effort Posts, No Info
Low-effort posts, such as those with only a link or video with no info, may be removed. Post clear questions. Research first. If sharing a project, explain what you are sharing and why. Is it yours or a random internet find? Do not post without providing some details, discussion, or thoughts to go along with it. What challenged you? When writing (asking OR bragging) about code, link to the source. Put it on GitHub or Pastebin. When asking about custom hardware, include full schematics.
No illegal or potentially dangerous projects
This is a public forum with people of all ages, motivations, skill and competency levels. Potentially harmful projects such as devices that can be used for widely illegal activities, weapons, interfering with medical devices, or other potentially harmful purposes—whether for personal use or not—are not allowed. If you are unsure about whether your project will fall into this category, contact the mods before posting. This includes anything with the intent of disrupting radio use by others.
Do not make off-topic posts
Posts need to be strongly related to the ESP32 series of chips or related technologies.
Urgency & language tips.
1) Your homework deadline, your bidding on a contract you can't fulfil, your overflowing septic system, etc. are—we're somewhat sorry to say—_your_ problem and not that of our 200k+ readers and contributors. Attaching urgency to your posts only irritates our regular contributors and doesn't get you an answer faster. Please don't do that. 2) Most participants of this group read and write English, even if via translation software. Please make it easy for them to help you. (Don't report them.)
Merchandise links - especially for Ali
Product links CAN be helpful. You shouldn't accept all deals on privacy. Please remove all referrer/tracking info (everything after the ? - esp. "tag" and "ref") when posting product links/URLs—especially with Amazon links or we may remove the posts. Most links to the Express of Ali are automatically removed before we even get to see them. (This is Reddit, not this group's mods making that deision) If your post/comment disappears, de-linkify it. e.g "Ali part number ZZZZZZZ".

What the written rules don't show

Unpublished minimums. Many communities remove posts from new or low-karma accounts through AutoModerator settings that are not on the rules page, often before a moderator sees them.
Reddit's own filters. Reddit's site-wide spam filters can remove posts from accounts that mostly share links to their own site, in any community.
The community's norms. Many communities see themselves as peers, not an audience: post where you already take part, and make the post worth reading without the link.

Let your AI read the rules before it posts.

ThreadFox reads a community's current rules, writes a post that fits them, posts once with Reddit's Brand affiliate tag and checks it stayed up. The free ThreadFox Lite reads rules too.
