box build assembly for IoT

When considering product development for smart applications, you may select Espressif's chips, such as ESP32, as the main control chip of the intelligent terminal. Why? Espressif's IoT chips and modules integrate Wi-Fi and Bluetooth functions, and you don't need to develop them yourself.

How to make your initial plan into real IoT devices? You will need PCBONLINE's box-build assembly service, including product R&D, PCB (printed circuit board) fabrication, PCB assembly, and box-build assembly at one stop.

Why Espressif IoT?

In the IoT (Internet of Things), wireless connection technologies include Bluetooth, Wi-Fi, NFC, ZigBee, NB-IoT, and Lora. All Espressif chips use Wi-Fi technology, including Wi-Fi 4 and Wi-Fi 6. Since the first ESP32 was released in 2016, the Espressif MCUs (Microcontroller unit) and modules integrate both Wi-Fi and Bluetooth technologies. Since the ESP32-C6 and ESP32-H2 were released in 2021 and the ESP32-C5 was released in 2022, the Expressif chips also support ZigBee technology.

Besides the connection supporting Wi-Fi, Bluetooth, and ZigBee, Espressif IoT chips provide the open-source and modular-mode development framework RISC-V. Compared with the other framework, ARM, RISC-V does not require authorization, supports modular design, and has strong scalability. Thus, you don’t need to pay for the expensive authorization in your IoT device development.

Here are some Espressif IoT chips, modules, and DevKits.

ESP IoT design guidelines

Besides the updates and iterations of the AIoT MCU and SoC (system on chip), Espressif creates open-source IoT development frameworks and platforms for building IoT applications. These frameworks include ESP-IDF, ESP-ADF, ESP-MDF, ESP RainMaker, ESP-WHO, and ESP-Skainet. For example, the audio development framework ESP-ADF can realize AI interactive functions, such as speech recognition, voice wake-up, echo cancellation, continuous dialogue, and voice control. The facial recognition development framework ESP-WHO's core function is face detection and recognition.

PCBA Box Build Assembly for IoT Devices

How to turn your IoT product design using ESP chips or modules into life? You will need PCBA box-build assembly, which is flexible production, to fabricate your IoT design from design to PCB assembly and final products.

An Espressif chip or module is an MCU or SoC that acts as the main chip of the board. Your IoT product design is developed based on the ESP chip or module that you select, so you need to carefully study the hardware design guidelines of the chip or module before the software and PCB design for your custom product.

If you lack enough R&D capabilities for PCB, software, and enclosure design, you can order the PCBA box-build assembly services to turn your initial plan into real products!

The one-stop PCBA manufacturer provides a box-build assembly for IoT applications using the Espressif MCU and SoC. The box-build assembly services include software and hardware R&D, PCB fabrication, PCB assembly, component sourcing for ESP chips/modules, and all the other required electronic parts, enclosures, and box-build assembly.

PCBONLINE, a source factory PCBA manufacturer founded in 1999, has two large advanced PCB manufacturing bases, one PCB assembly factory, and an R&D team. We provide one-stop electronics manufacturing and R&D for your Expressif IoT projects until the final product delivery.

If you need one-stop PCB assembly for DC/AC converters or any other electrical or electronic devices, you can work with the EMS (electronic manufacturing service) PCBA manufacturer PCBONLINE. PCBONLINE provides PCB fabrication, component sourcing, PCB assembly, box build assembly, and R&D to meet your custom electronics manufacturing demands at one stop.

An ESP PCBA Example

ESP PCBA

This is an ESP PCBA manufactured by PCBONLINE for intelligent sensor products. During the IC programming or burning process, we encountered a problem with an insufficient power supply.

The ESPRESSIF module is the component for burning. Initially, we suspected either a voltage or software issue, but after conducting an online meeting with our clients' engineering team, it became clear that this was not the case.

The issue with the power supply voltage has been resolved, yet the "SYNC" error message (indicating insufficient power to function properly) still appears. What could be the cause of this persisting problem?

Our engineer, Mr Ho, spent two hours constantly testing and troubleshooting and finally focused on the burning tool while maintaining the short circuit between the two pins. The key was on "Cold Boot"!

Yes, in the case of direct access, you need to manually remove the GND connection port again and install the connection twice. Then, the burning program can run successfully!
