Internet of Things with ESP32

Created by Espressif Systems, ESP32 is a low-cost, low-power system on a chip (SoC) series with Wi-Fi & dual-mode Bluetooth capabilities! The ESP32 family includes the chips ESP32-D0WDQ6 (and ESP32-D0WD), ESP32-D2WD, ESP32-S0WD, and — coming soon — the system in a package (SIP) ESP32-PICO-D4. At its heart, there's a dual-core or single-core Tensilica Xtensa LX6 microprocessor with a clock rate of up to 240 MHz. ESP32 is highly integrated with built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules. Engineered for mobile devices, wearable electronics, and IoT applications, ESP32 achieves ultra-low power consumption through power saving features including fine resolution clock gating, multiple power modes, and dynamic power scaling.

Features & Specifications

(ESP32 Function Block Diagram)

See the ESP32 Datasheet for information on dual-core ESP32 chips. Additionally, see the ESP32-S0WD Datasheet for information on the single-core ESP32 chip and the ESP32-PICO-D4 Datasheet for information on the SIP module.

Clarification note: In this context, "RTC" is a bit of an "Espressifism" because it's used as shorthand for the low-power and analog subsystem which is separate from the CPU and the main "digital" peripherals ("digital" is another Espressifism). There is some real time clock functionality as part of the RTC subsystem, but there's also a lot of other stuff.

Community & Discussion

Real-time chat via IRC is a great way to converse with others, learn new things, and sometimes get answers to questions on the spot. Having said that, the main drawback to online chat is that not everyone is active or looking at the channel (chat room) at the same moment — people work at different hours and live in different parts of the world — so timing can be hit-or-miss. So, if you ask a question in the channel, try to stick around for awhile, as it might take someone awhile to respond. For many questions, it's often better to submit a post in the forums, as that will typically have greater visibility to others, and is less dependent upon the immediate here and now and the ephemeral nature of online chat.

Hardware

QFN Packaged Chips

The ESP32 SoC (system on a chip) is housed in 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.

ESP32-PICO-D4 has been included on the following boards:

Compact SMT 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.

Small & Medium Development Boards/Modules (SMT PCB Module‑Based)

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 SMT 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.

Features an xBee socket with switchable VCC voltage (3.3 V or 5 V), so 2G (SIM800) and 3G (SIM5360) xBee modules will work on it to provide cellular network access. The second and third serial UARTs can be accessed from two onboard 4-pin connectors, which the Freematics OBD-II adapter and GPS receiver can be hooked on.

Purchasing

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 SMT module) for easier hardware setup and an better first time experience. Espressif's official, publicly sold development boards are ESP32-DevKitC and ESP-WROVER-KIT.

Note about Taobao: Those unfamiliar with Taobao should read Naomi Wu's article, "Source Parts on Taobao: an Insider's Guide" before attempting to make a purchase through the venue.

Chips

A few words of clarification because some people have erroneously confused chips with SMT 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 SMT 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.

Development Boards/Modules

In contrast to compact SMT 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 SMT modules with FCC IDs (such as the Espressif ESP-WROOM-32, Espressif ESP32-WROVER, or Ai-Thinker ESP-32S module) will have that SMT module component certified.
