Minecraft on calculator Bilibli on calculatorĭevelopers installed some apps through adb, after enabling Android’s developer options, such as Minecraft and Bilibili, and some people simulated PSP and PS simulators on it. A small screen with the Allwinner A50 can also be used as a small tablet. Many developers have already purchased the calculator at very low prices, and a phrase has been circulated in a pan-tech digital community in China that reads, “As long as there is a screen, you can root the system of the device”. So I guess this should be 8GB, and there is a footprint for another chip beside it, which I suspect is for a NAND flash. I just saw that 61% of the system storage is used, and there are still 3 GB left. You may be able to buy another calculator if you take them apart and sell them. So many DDR chips on one calculator are a bit of a luxury. There are four identical DDR chips here, Samsung SEC K4B2G0446D, 2Gbit D-die DDR3L SDRAM. The reason why the price is so low may be that it reduces the cost of software development on the A50. Looking back at the A50 animation at the time of startup, I feel that this is the A50 standard tablet case given by the official of Allwinner in the early years. Interestingly, these two chips, like the A50, are designed by Allwinner. Next to them are the AXP2231 PMIC and the XR829 wireless chip. Package – FBGA 413balls, 12.3mm x 12.8mm size, 0.5 ball pitch, 0.3 ball size.Up to 2x I2S/PCM controllers for connecting Bluetooth and external audio codec.3x analog audio inputs and 1x analog audio output.RGB interface with DE/SYNC mode up to 1920 x 1080 60fps.4-lane MIPI DSI output up to 2048 x 2048.8-bit TLC/MLC/SLC/EF NAND flash with support for FDE.eMMC 5.0 flash with support for Full Disk Encryption(FDE).Memory – 32-bit DDR4/DDR3/DDR3L/LPDDR3/LPDDR4.You can get more details in the product brief. Allwinner A50Īllwinner A50 is a tablet chip launched long ago with Mali-400MP2 GPU that is suitable for tablets up to 1920 x 1080 resolution. ![]() GHLBD BoardĪnother part should be the calculator’s control motherboard, you can see that there are a lot of ICs above. Behind the lithium battery, we’ll find the keyboard PCB (green). You can see that there is a USB Type-C interface for charging next to it, However, I have not yet tested the actual usage time of the calculator and have no official data to refer to. The calculator is equipped with a 2,700mAh lithium battery. You can clearly see the words “Quad-CORE A50” and “Android 9.0” Android calcultator teardown Keyboard baseboard and battery System InformationĮnter the “System Settings” interface from the menu bar. It is likely that the engineer has removed the default launcher from the Android system, which will lead to this situation. I try to return to the Android desktop by clicking several buttons at the bottom of the screen, but it directly returns to the menu bar at the beginning and displays “No recent content”. The drop-down menu at the top is obviously Android’s notifications bar. In addition to the functions of the calculator itself, the user interface also includes a calendar,a notepad, calculation history, WiFi networking, volume setting, and other functions. I think Allwinner A50 is fully capable of performing such complex calculations, and I don’t understand why they didn’t implement this function. This calculator can only perform simple calculations and has no “scientific calculator” mode for more complex functions. Here, you can preliminarily confirm that the promotional content is accurate and that I got an Android calculator. The Allwinner A50 processor icon and Android logo show up in the boot animation. Press and hold the ON and OFF keys on the keyboard to turn on the calculator. Function demonstration of GHLBD calculator Power on animation I decided to introduce it and disassemble it to check out the hardware design. I didn’t really have a use case for it, but curiosity drove me to buy one. When I bought it, I only spent 69 RMB ($10 US). If you only look at the appearance, this calculator is not much different from that of ordinary calculators, but the Android operating system is running on it and the screen tells me that it is definitely not an ordinary calculator. Three labels of this product appeal to me: “Calculator”, “Android 9.0” and “ Allwinner A50“. I found this GHLBD calculator on a platform selling second-hand electronic products. ![]()
