The SCR3's other controls consist of a recessed power button in bright orange, dedicated Escape and Delete keys, the aforementioned Shift control, and a Backup button for saving SIM contacts to the SCR3. That being the case, we're willing to let it pass.
It's not the most ideal arrangement (as it cuts down your typing speed), but we get that adding more dedicated buttons would have increased the SCR3's size. Rather, a few of the letter keys do double duty for numbers and symbols when used with the Shift button. It's important to note that there are no dedicated numeric or symbol keys. We were able to type quickly while avoiding mistakes, even if the keys could use a darker color to give them more definition. The raised keyboard buttons are relatively large and also have a tactile feel that makes them comfortable to use. They're sufficiently big and they have a slightly rubberized feel that makes them very tactile.īelow the display are nine round blue buttons that give you one-touch access to various features while the keyboard sits below them. On either side are control buttons for scrolling through lists and for moving the cursor around the display. Also, you can change the screen's brightness. The display uses simple block text, so it's not very pretty but the text is large and easy to see in all lighting conditions. Lift it up and you'll notice the two-inch monochrome display and a range of buttons. The SCR3 is protected by a clear plastic cover. The gray-and-blue color scheme isn't terribly attractive-simple black would have been nice-but the see-through bottom cover lets you view the SCR3's inner workings.
At 4.5 inches long (it's used horizontally) by 3.0 inches wide by 0.5 inch thick and weighing in at 3.2 ounces, it's much bigger than the SCR1 and the SCR2 (due to the QWERTY keyboard), but it's still small and light enough to take on the go. It's a simple but nifty idea that still hasn't been mass-produced. Using the SCR3, you can back up the contacts from your cell phone's SIM card for safekeeping. It may look like the 1980s calculator you received after subscribing to a magazine, but it has a decidedly modern function. Technical parameters can be found in the attached datasheet.Don't let the SCR3's design scare you off. Operating temperature : -30 ° to + 85 ° C.
The SIM card reader are intended for use in devices that support GSM technology, such a sales terminals, smart meters, surveillance cameras and security cameras. The spring on the side prevents the SIM card from sliding.Įasy connection and disconnection, guarantee is 5000 cycles. The card holders also have polarization functions for the correct orientation of the SIM card. The button must be pressed to release the latch. The holder is equipped with an active latch that prevents the SIM card from sliding out of the connector, eg due to vibration. The rear stop ensures the reliable connection of SIM card and the connector. For easy insertion or removal of the SIM card from the holder, the ChipSim connectors are equipped with a slide-out mechanism. The SIM card reader is intended for use with removable SIM cards in devices based on GSM communication. LPWAN antennas - NB-IoT, LoRa, Sigfox, 868 MHz (11).
