ODM Manufacturing and Self-Developed Active Components

pcbonline PCBONLINE Team Mon, Mar 13, 2023

ODM stands for original design manufacturing or original design manufacturer, which means a company designs and manufactures electronic products according to the requirements of its clients.

In recent years, the fabrication price of electronic products has always been lifting mainly due to the soaring active component prices, especially IC chips. Plus the designing fee, you may have been worried about your limited project fabrication budget. But no worries! You have chances to access the most affordable ODM services using self-developed components.

The advanced PCB OEM manufacturer PCBONLINE maintains cooperation with two design companies to provide you with ODM manufacturing. Our two partners provide R&D to meet your application specifications and fabricate active components developed by themselves.

You can order ODM manufacturing from us based on the self-developed active components. Our partners now have ready-to-use solutions and products for defense systems, forest fire prevention, and water meters. If you want ODM manufacturing for electronic uses using these affordable chips, you can email us at info@pcbonline.com.

McM485 Half-Duplex Transceiver

McM485 is a half-duplex RS-485 transceiver. This product uses a swing limiting driver, which can significantly reduce EMI and reflection caused by the improper terminal matching cable and can achieve error-free data transmission of up to 10Mbps.

McM485 has a built-in failure protection circuit to ensure that the output of the receiver is in a logic high-level state when the input end of the receiver is in an open circuit or short circuit. The input impedance of the receiver is 1/8 unit load, which allows up to 256 transceivers to be connected to the bus to realize half-duplex communication.

McM485 can be the perfect functional alternative to MAX3485, SN75176, and ADM3064E, which has a better price and LT.

MCM78SPI wireless module

MCM78SPI wireless module is a radio frequency module based on LORA technology. It is a high-performance wireless transceiver of the Internet of Things. Its special LORA debugging mode can greatly increase the communication distance and can be widely used in the short-range wireless communication field of the Internet of Things on various occasions.

It has the characteristics of small size, low power consumption, long transmission distance, strong anti-interference ability, and so on. According to the actual application, there are a variety of antenna schemes to choose from.

The functional features of this module are as follows:

  • Working voltage: 1.8V~3.7V
  • Working frequency band: 410MHz-525MHz
  • Transmitting power: 19±1dBm (max)
  • Ultra-high reception sensitivity: -136±1dBm (@ 250bps)
  • Ultra-long effective communication distance: 5Km@250bps (open distance)
MCM78SPI wireless module

In the MCM78SPI wireless module, spread spectrum technology is used for communication. In the same urban and industrial application environment, the performance is better than that of RF products working with traditional modulation methods (FSK, 2-FSK, 4-FSK, GFSK, PSK, ASK, OOK, etc.). In the harsh noise environment (near strong interference sources such as meters and motors, and natural shielding environments such as elevator shafts, mines, and basements), the advantages are particularly obvious.

Besides the other metrics, the MCM78SPI wireless module has these features:

  • High confidentiality: the LoRa modulation mode is adopted, and traditional wireless devices cannot capture and analyze it.
  • High concealment: normal communication can still be achieved when the average power in the band is lower than the bottom noise.
  • Good capability: LoRa modulation mode is adopted, and FSK, GFSK, and OOK traditional modulation modes are compatible and supported.
  • Low power consumption: receiving current ≤ 13mA, Sleep current ≤ 1uA. The CAD function is provided to separate calculation from signal reception and further optimize wake-up window power consumption (the calculation current is about half of the received current).
  • Support hardware frequency hopping (FHSS). Combined with LoRa's spread spectrum technology, the MCM78SPI wireless module achieves ultra-strong communication concealment and security. SPI communication interface: can be directly connected to various single-chip computers for use, and software programming is very convenient.

ODM Applications Based on the Self-Developed Active Components

ODM serves original equipment manufacturers (OEMs), business makers, and research institutes, especially those companies that have their brand and specialize in sales but lack R&D and manufacturing capabilities. ODM manufacturing can be used in every electronic field. There are the below ready-made solutions our partners created using their self-developed IC chips.

Civil air defense system

Our partners have designed and made the ODM samples to be used in the defense system. You can contact us to try our ODM services. There are self-developed LoRa gateways, oxygen sensors, carbon dioxide sensors, atmospheric pressure temperature and humidity sensors, inclination sensors, and fan control terminals.

Forest fire prevention

There are the independently developed LoRa gateway, gateway relay, and forest fire protection temperature sensors, which can be used for forest fire prevention.

The sensor data can be directly sent to the gateway through LoRa for a short distance and can be sent to the gateway through the gateway relay for a long distance. The maximum visible distance is 5 kilometers. A single gateway plus relay can monitor sensors with a radius of 10 kilometers. The temperature data can be sent to the cloud through 4G. If the local 4G network signal is not good, the data can also be sent through the Beidou Satellite System.

Water meter

Based on LLCC68's self-developed concentrator and water meter module, the power consumption of the water meter module is very low, and the single service life can be up to 6 years without replacing the battery.

There is also a valve control function, which controls the switch of the water meter. The water meter module also supports the relay function so that a single concentrator can control more modules. A single concentrator can read and control 1000 water meter modules. It supports multiple functions, such as a network to read water meter data, independently read data of a water meter, control water meter valves, etc. Certain cloud platforms, application data, and payment data could be very important and valuable.
