  • 加密硬件加速：AES，SHA-2，RSA，椭圆曲线加密（ECC），随机数发生器（RNG）

  澄清说明：在这种情况下，“RTC”有点像“Espressifism”，因为它被用作低功耗和模拟子系统的简写，它独立于CPU和主要的“数字”外围设备（“数字”是另一个Espressifism）。作为RTC子系统的一部分，有一些实时时钟功能，但还有很多其他的东西。

对于大多数问题，最好在论坛中提交一篇文章，以获得最广泛的社区可见性，并轻松写出您的情境背景的细节 - 例如，包括示例代码和详细说明软件的相关配置，固件和 硬件。 或者，通过IRC进行实时聊天是与他人交谈，学习新事物，有时在现场获得问题答案的好方法。 但是，话虽如此，在线聊天的主要缺点是，不是每个人都在活跃或同时看着频道（聊天室） - 人们在不同的时间工作并生活在世界的不同地方 - 所以时间可以是 击中或没打中。 因此，如果您在IRC频道中提出问题，请尽量留意，因为可能需要一段时间才能回复。

Hardware listed below includes the Quad-Flat No-Leads (QFN) packaged ESP32 chips and system-in-package module, various surface-mount printed circuit board modules, a large variety of development boards, and industrial, commercial, and general consumer devices.

QFN Packaged Chips

The ESP32 SoC (system on a chip) is housed in surface-mount, Quad-Flat No-leads (QFN) packages in either 6×6 mm² or 5×5 mm² sizes with 48+1 connection pads (48 pads along the sides and one large thermal pad connected to ground on the bottom). Physical package footprint/dimensions can be found in chapter 6 of the ESP32 Datasheet. All ESP32 chips thus far have been manufactured using TSMC's ultra-low power 40 nm process.

QFN Packaged Module

ESP32-PICO-D4 SiP (system in package) module is housed in a 7×7 mm² Quad-Flat No-leads (QFN) package with 48+1 connection pads (48 pads along the sides and one large thermal pad connected to ground on the bottom). Package footprint/dimensions can be found in the ESP32-PICO-D4 Datasheet.

PACKAGE SIZE NOTES ESP32-PICO-D4 Dual-core 4 MiB 7 mm × 7 mm SiP module combines ESP32 silicon, crystal oscillator, flash memory, filter capacitors, and RF matching links into a single package. Datasheet Photos: Size comparison to €1 coin Internals photo Known manufacture dates: LOT NUMBER YEAR WEEK TJAGAPOP95 2017 28th Pins GPIO16, GPIO17, SDCMD, SDCLK, SDDATA0 and SDDATA1 are used for connecting the embedded flash, and are not recommended for other uses. ⚠️ Announced on 2017 Sept 1, although its existence was publicly known before. ESP32-PICO-D4 has been included on the following boards:

Espressif: ESP32-ZERO V2 (surface-mount PCB module), ESP32-PICO Core Board V2, ESP32-PICO-KIT (ESP32-PICO Core Board) V3 & V4 Microwavemont: ESP32-PICO Motherboard, ESP32-PICO-ADB, ESP32-PICO Double Decker, ESP32-PICO-CAM, ESP32-PICO-tinyCAM Compact Surface-Mount PCB Modules

The ESP32-based Wi-Fi/Bluetooth communication modules in the table below are surface-mount devices (SMD). Each module is a small printed circuit board upon which chips and other components are soldered and treated as an inseparable assembly to be integrated onto another PCB. All the modules listed below contain an ESP32 chip, a 40 MHz crystal (clock), and a flash memory chip, but vary in features such as antenna configuration, capacity of the flash memory chip, and EM shielding. Because these wireless communication module boards are designed for incorporation into final products (unlike development boards), they lack development components which are unnecessary or undesirable in final products — e.g., typically no USB-to-UART nor programming/reset buttons — minimizing both cost and physical size.

Note that the pSRAM column refers to inclusion of additional on-board pseudostatic RAM; this figure does not include the SRAM within the ESP32 chip itself.

Small & Medium Development Boards/Modules (Not Using PCB Module)

These small and medium sized development boards have USB-to-UART interfaces, but the ESP32 chip is directly incorporated into the board (instead of using a ESP32-based surface-mount module).

Small & Medium Development Boards/Modules (Using PCB Module)

Development boards are designed to be easily worked with for the purpose prototyping and development. Typically this means connections are broken out with 0.1″ spaced headers (in contrast to the more tightly spaced connections seen on the compact surface-mount module boards). Furthermore, development boards often contain on-board components to aid in easy prototyping & programming — e.g., power-supply/regulation, USB-to-UART, and buttons for flashing & resetting.

Disclaimer: Vendors are listed here for informational purposes only. Buyers should use prudence and careful judgement when ordering. Before ordering, read all product descriptions and check vendor ratings when possible. Prices listed below are approximate and do not include shipping costs. Furthermore, prices listed below may be outdated, so be diligent and check for yourself.

Note to the beginner: If you are just getting started and don't know what to purchase, it would probably be best for you to purchase a development board (instead of an surface-mount module) for easier hardware setup and an better first time experience. Espressif's official, publicly sold development boards are ESP32-PICO-KIT, ESP32-DevKitC, and ESP-WROVER-KIT.

Note about Taobao: Taobao is a Chinese marketplace. For international shopping, intermediary agents are often used (for a fee, of course). Those unfamiliar with Taobao should read Naomi Wu's “Source Parts on Taobao: an Insider's Guide” and Eric's “How to Buy Directly from Taobao” before attempting to make a purchase through the venue.

QFN Packaged Chips

A few words of clarification because some people have erroneously confused chips with surface-mount PCB modules: If you wish to purchase just the Espressif ESP32 chip itself, understand that this means you're only receiving the fabricated silicon contained within a tiny Quad-Flat No-leads package. For those seeking integration/inclusion of ESP32, using an surface-mount module board with ESP32 inside is often more desirable, since such modules combine an ESP32 chip, 40 MHz crystal (clock), flash memory chip, and appropriate “glue” components into a ready-to-use, compact assembly. Having said that, if you wish to purchase only the chip and not a module board, you can purchase the chip through vendors listed below. You can also find sellers in venues like eBay and AliExpress using search queries with “ESP32” and “QFN”, “SMT”, “SMD”, “package”, “bare” or “raw”; also using the full identifier (such as “ESP32-D0WDQ6” or “ESP32-D2WD”) in search queries may prove fruitful.

In addition to the sellers listed below, you can contact Espressif directly for chip purchase inquiries. For small quantities, Espressif will likely direct you to an appropriate distributor to contact. If you are a distributor or otherwise interested in ordering a large quantity of parts, the minimum order quantities for parts direct from Espressif are listed in the Espressif Products Ordering Information document.

Development Boards/Modules

In contrast to compact surface-mount modules, development boards break out connections to be larger and more “human scale” for easier prototyping and development and frequently include additional circuity and interfaces for power supply and programming.

Pycom WiPy 2.0 (FCC ID 2AJMTWIPY2R), Pycom LoPy (FCC ID 2AJMTLOPY1R), and Pycom SiPy (FCC ID 2AJMTSIPY1) development boards/modules have received FCC IDs. Development boards that employ surface-mount modules with FCC IDs (such as the Espressif ESP-WROOM-32, Espressif ESP32-WROVER, or Ai-Thinker ESP-32S module) will have that module component certified.
