Review of PiFinger: High-performance Fingerprint HAT for Raspberry Pi
PiFinger comprises a High-speed Processor, a High-performance fingerprint algorithm, and a Flash chip that increases its efficiency. PiFinger consists of a sensor that is based on capacitive coupling. It can detect and measure anything that is conductive or has a dielectric, different from the air. The sensor has a hardened surface and enhanced ESD immunity. PiFinger is programmed to compare and register at most 24 fingerprints as well as recognition algorithms for fingerprint comparison. It works with high accuracy because of the high comparison speed that enhances the quality of work.

High Performance of PiFinger
It offers an indistinguishable experience of PiFinger HAT that would raise the level of curiosity to learn about the people. PiFinger, the first-ever Fingerprint HAT for Raspberry Pi Comprise of onboard Nuvoton MCU with an on-chip crypto-accelerator, Cortex-M23 TrustZone, and XOM facilities has launched on 25th of November that priced at £36 at the super early bird discount. A person can use the communication protocol to the PiFinger with commands over the UART protocol with the Baud rate 115200 bps or USB 2.0 full speed.
Open-source License
PiFinger is one of the powerful devices that comes with the open-source license that people can use in their DIY projects or their industries. Inside the PiFinger, there is a robust fingerprint sensor that runs on capacitive-contact technology, which is a 2D capacitive fingerprint sensor with an active scanning area of 8.8 x 8x8 mm, and a resolution of 176 x 176 pixels.
Huge discounts for early birds
SB Components organization developed PiFinger to enhance the efficiency of its users. We launched PiFinger on the 25th of November 2020 to get support from our users. We are giving a huge discount for our super early bird at £36 to make our customers get a steal deal. You can check out the product on this link to get more information about the product. We are offering one of the best deals for the PiFinger to our customers to make them save money on a robust and compact device.
PiFinger Specifications
PiFinger is powered by an onboard Nuvoton MCU with an on-chip crypto-accelerator, Cortex-M23 TrustZone, and XOM facilities. Nuvoton MCU also works as an interface IC and control unit on the board of PiFinger that provides accuracy with power simultaneously. You get UART protocol with the Baud rate 115200 bps or USB 2.0 full speed for the communication. It has an OLED display of 0.91” and has a storage capacity of 24 fingerprints. PiFinger consists of a 40 pin GPIO header and LED indicators. The matching model of the PiFinger is 1:1; 1:N.
Why should you buy PiFinger?
PiFinger has a powerful sensor that would scale up the quality of the system of the devices. The sensor of PiFinger has the 2D capacitive Fingerprint area sensor with a sensor array of 176x176 pixels. It has a 508 DPI spatial resolution with an 8-bit pixel value/256 gray level that raises the quality of PiFinger. The sensor communicates with the board of PiFinger from the High-speed SPI interface. It has an Image capture speed up to 2MP/sec and consists of the 8.8mm x 8.8 mm active sensing area. The image ratio of length to width is 1:1. If we look at the ESD protection then it is +/- 15kV(Air mode).
Backer Centric Project
PiFinger has launched in the market and it needs the support of the people to become successful. SB Components developed the PiFinger that comes with a built-in fingerprint matching capability and has high accuracy while leaving chip resources(Most of it) to developers of the application. A user can develop various Fingerprint related products with the basic knowledge of fingerprint identification. PiFinger can perform functions like Fingerprint storage, Fingerprint scan, Comparison( 1:1), and Search (1:N). It is one of the advanced products that can help in your DIY projects and commercial applications as per the requirements.
We are looking for people who are excited about our brand and want to contribute to the growth of the brand. We promise 100% guaranteed high-quality products within the expected delivery time. We have working prototypes in the hands of professional developers right now, and we have machines that are ready to work for our customers.
