Features of the compact Wi-Fi module BP3595
"BP3595" is a compact Wi-Fi module with built-in antenna provided by ROHM, and has the following features.
- 2.4GHZ
- IEEE802.11b/g/n compliant
- IEEE802.11i (security standard)
- TCP/IP protocol stack can be installed (UART I/F)
- Small size (15.3mm×27.6mm)
- Built-in antenna
- 3V single power supply
- Equipped with USB, SDIO, and UART interfaces
- Operating temperature: -40~85 degrees
Therefore, it is ideal for applications such as cooperation with smart home appliances, surveillance cameras, smartphones, and tablets.
Reliable long-term supply
All ROHM Wi-Fi modules are manufactured in Japan. In addition, baseband LSIs, modules, and software are all produced by ROHM.
As a result, we are able to provide long-term supply even when the production of key devices is discontinued.
Only 15.3mm x 27.6mm with built-in antenna
The "BP3595" module is equipped with a chip antenna. Therefore, the user does not need to do any external antenna design. High frequency design for external antenna installation is not required.
In addition, despite its extremely small size of 15.3mm x 27.6mm, the BP3595 alone can be used as a Wi-Fi module. This makes them ideal for space-constrained applications such as smart home appliances and surveillance cameras.
Radio certified in Japan
"BP3595" has acquired radio wave certification in Japan. Therefore, there is no need for users to newly acquire radio wave certification in Japan.
Since the cost and period for radio wave certification can be shortened, mass production of products can be started immediately after product development.
*Specified radio equipment type: Article 2, Paragraph 1, Item 19, Radio Equipment, 2.4 GHz Band Advanced Low Power Data Communication System” and “Construction Design Certification” (Article 38-24, Paragraph 1 of the Radio Law) have been obtained. am.
Built-in TCP/IP stack eliminates the need for driver development (UART I/F)
If the "BP3595" Wi-Fi module interfaces with the host microcontroller via UART, ROHM provides firmware with a built-in TCP/IP protocol stack. Therefore, wireless LAN device driver development is unnecessary.
In addition to the TCP/IP stack, it also has authentication processing and WPS functions, and since network processing can be processed on the module side, there is no load on the host.
Therefore, Wi-Fi can be installed in applications that were difficult to install due to lack of host resources.
In addition, since there is no need for driver development, the development period can be greatly shortened.
* Supplicant = software that processes authentication, encryption, etc. that conforms to wireless LAN standards
Evaluation kit for immediate operation check
The BP3595 comes with an evaluation kit that allows immediate evaluation by connecting to a PC. The equipment required for evaluation is as follows.
- 1 PC
- BP3595 (Wi-Fi module)
- BP359F (adapter board)
- BP359C (UART I/F board)
After that, you can start evaluating the Wi-Fi module immediately by downloading the sample program from ROHM's website.
Application example
- digital consumer electronics
- AV equipment
- sensor network
- home network
- smartphone, tablet
