ESP8266 modules are still selling by the millions (Sponsored)

The ESP8266 Series WiFi modules were designed by Ai-Thinker in 2014. Since its launch, it has been widely welcomed by customers around the world due to its high cost-effectiveness and powerful performance. Even with the launch of the ESP32 a few years ago, the demand for ESP8266 has not abated, with so far, the sales volume in 2021 exceeding 30 million units with the ESP-01S/ ESP-07/ESP-12F/ESP-12S being the most popular ESP8266 modules.

ESP8266 50 million units sold

ESP8266 supports the standard IEEE802.11 b/g/n protocol with a complete TCP/IP protocol stack. Users can use this module to add networking functions to existing equipment or build an independent network controller. ESP8266s are high-performance wireless SoCs that provide maximum practicability at the lowest cost and provide unlimited possibilities for Wi-Fi functions to be embedded in other systems.

ESP8266 Characteristics

  1. Built-in Tensilica L106 ultra-low power consumption 32-bit micro MCU, main frequency supports 80 MHz and 160 MHz, supports RTOS.
  2. Built-in 10 bit high precision ADC.
  3. Wi-Fi @ 2.4 GHz, supports WPA/WPA2 security mode.
  4. Support AT local upgrade and cloud OTA upgrade
  5. Support Smart Config function (including Android and iOS devices)
  6. HSPI, UART, I2C, I2S, IR Remote Control, PWM, GPIO
  7. Deep sleep hold current is 20 uA, shutdown current is less than 5 uA
  8. Wake up, connect and transmit data packets within 2 ms
  9. Standby power consumption is less than 1.0 mW (DTIM3)

ESP-01S module

ESP-01S

The processor supports 80 MHz and 160 MHz frequencies, runs FreeRTOS real-time operating system, and integrates Wi-Fi MAC/BB/RF/PA/LNA as well as on-board PCB antenna. The pre-loaded firmware support Android/iOS Smart Config, AirKiss one-key configuration network, and general AT commands.

ESP-07S module

ESP-07S

The ESP-07S is our most compact ESP8266 module offered in an SMD-16 package (17x16x3mm) for easy soldering. It can be used in standalone mode booting from the 32 Mbit flash or as a slave connected to a host microcontroller through an up to 4 Mbps UART interface.

ESP-12S module

ESP12-S

The ESP-12S is another tiny module that contrary to ESP-07S comes with a built-in PCB antenna. The ESP8266 module can be integrated into an MCU-based design through SPI/SDIO or UART interfaces, and like out other modules also provides expansion I/Os with up to 9 GPIO, UART, ADC, PWM, SPI, and I2C.

ESP-12F module

ESP-12F

The ESP-12F module is a hot-selling module on the international markets thanks to its many global and country-specific certifications, including RoHS, REACH, FCC (USA), CE (Europe), SRRC(China), IC (Canada), KCC (South Korea), NCC (Taiwan, China), ANATEL (Brazil), and TELEC (Japan).

 

Applications for AI-Thinker ESP8266 modules

Our modules have already been used in many types of applications and sectors with, just to name a few, Smart Transportation, Sensor Application, Smart City, Wireless Monitoring, Smart Home, Smart Door Lock, and the list goes on.

I doubt anyone would disagree with this article even if it wasn’t sponsored. Most of us have used dozens of these modules ourselves. I’m not more than a foot from one right now. Keep up the good work, Espressif.

+1 as well. These devices have really ignited the IoT trend.

One thing that’s still ESP8266 exclusive is the Sming framework

https://github.com/SmingHub/Sming

Which makes programming micros really nice. A nice middle ground between Arduino and trying to grok some HAL

I would call esphome the most exlusive thing available for esp82xx and esp32.

One to rule them all.

I really wonder why ai-thinker didn’t mention the new esp-c3 (risc-v esp32 single core) family which have pin compatible modules for esp-12f and others. Perfectly to retrofit.

Maybe for another post. They have more planned.

Is their any reason this sponsored post has comments open but the newest one from udoo has comments disabled?

Probably because people would comment that the $4 pledge level was already filled before the article even went up making the headline a bit misleading? 😉

I ordered some ESP01 modules for a workshop in Berlin in 2014.

Those modules were a pain in the ass to work with, custom baudrate bootloader, 3.3v supply, etc…

Companies still have not learned that they need to open source the wifi stack as well.

7 years later and now no one complains about 3.3V devices as they’re the norm. The bootloader is well supported and documented. The custom baud rate is still there, but doesn’t matter much unless you’re debugging boot issues and then that’s not really all that different from any other device that needs specialized hardware to debug, is it? I do wish the wifi stack was more open, but that’s probably partially a regulatory acceptance issue. If you haven’t worked in international regulatory compliance and appreciate all the limitations and complexities, you may not understand why things are done they way… Read more »

I do understand the excuse of radio compliance, the EU is trying to push on radio lockdown, and the ban of users controlling their radio, defacto accepting binary blobs (and potential spywares in there). From a security and auditability perspective, this is not acceptable. In 2014, I found by doing a ‘strings’ in the Espressif binary the address of an IOT server.

I agree that those are valid concerns and I share them. I’m at a loss as to what we can expect of Espressif to address it. They’re in a bit of a catch-22 between regulation and the desire for openness.

I’m curious about that IOT server. Did you look to see what was happening with it?

Jon Smirl

There is no win for Espressif on this one. Keeping this closed is being pushed by various governments. This is impacting all wifi vendors.

I don’t know if the IP address still in the binary, but if it is, it is likely a regulatory server so that the BLOB can be updated with new frequency restrictions as the laws change.
