This is a very nice part, that can be easily attached to Arduino systems. I had to dig around a bit to find and configure the correct library (see below) but it works great. 30 Years ago, you would have paid a small fortune for this! I 3D printed a part to mechanically line up the three modules and now use it as one large part with 12 positions. Here is the most important code: // Program to exercise the MD_MAX72XX library // configuration for Nano v3 with 12x 1088AS // // Uses most of the functions in the library #include #define HARDWARE_TYPE MD_MAX72XX::FC16_HW #define MAX_DEVICES 12 #define CS_PIN 10 // or SS // SPI hardware interface MD_MAX72XX mx = MD_MAX72XX(HARDWARE_TYPE, CS_PIN, MAX_DEVICES);

Very nice small Humidity + temp display. Quick delivery. Unit itself cannot be placed in high temperature environment: the display becomes unreadable (recovers when put back at room temperature)

Have not had the change to try out yet (waiting for the LiFePo cells). Unit looks good - quick delivery.

This is a very nice part. Had some trouble to find the right library for an Arduino Nano to get it to work. Here is the code: // Program to exercise the MD_MAX72XX library // configuration for Nano v3 with 12x 1088AS // // Uses most of the functions in the library #include // Turn on debug statements to the serial output #define DEBUG 1 #if DEBUG #define PRINT(s, x) { Serial.print(F(s)); Serial.print(x); } #define PRINTS(x) Serial.print(F(x)) #define PRINTD(x) Serial.println(x, DEC) #else #define PRINT(s, x) #define PRINTS(x) #define PRINTD(x) #endif // Define the number of devices we have in the chain and the hardware interface // NOTE: These pin numbers will probably not work with your hardware and may // need to be adapted #define HARDWARE_TYPE MD_MAX72XX::FC16_HW //#define HARDWARE_TYPE MD_MAX72XX::DR0CR0RR0_HW //#define HARDWARE_TYPE MD_MAX72XX::DR0CR0RR1_HW //#define HARDWARE_TYPE MD_MAX72XX::DR0CR1RR0_HW //#define HARDWARE_TYPE MD_MAX72XX::DR0CR1RR1_HW //#define HARDWARE_TYPE MD_MAX72XX::DR1CR0RR0_HW //#define HARDWARE_TYPE MD_MAX72XX::DR1CR0RR1_HW //#define HARDWARE_TYPE MD_MAX72XX::DR1CR1RR0_HW //#define HARDWARE_TYPE MD_MAX72XX::DR1CR1RR1_HW #define ver "FC16_HW" #define MAX_DEVICES 12 #define CLK_PIN 11 // or SCK #define DATA_PIN 12 // or MOSI #define CS_PIN 10 // or SS // SPI hardware interface MD_MAX72XX mx = MD_MAX72XX(HARDWARE_TYPE, CS_PIN, MAX_DEVICES); // Specific SPI hardware interface //MD_MAX72XX mx = MD_MAX72XX(HARDWARE_TYPE, SPI1, CS_PIN, MAX_DEVICES); // Arbitrary pins //MD_MAX72XX mx = MD_MAX72XX(HARDWARE_TYPE, DATA_PIN, CLK_PIN, CS_PIN, MAX_DEVICES); // We always wait a bit between updates of the display #define DELAYTIME 100 // in milliseconds void scrollText(const char *p) { uint8_t charWidth; uint8_t cBuf[8]; // this should be ok for all built-in fonts PRINTS("nScrolling text"); OOPS: cannot post more than 2000 characters...

I have high expectations for this part. I think it is great to have the ESP32 / SIM7600 combination on a single board! For me this replaces the older Arduino Mega with the SIM7000 LTE modem boards, at lower total cost. What would be REALLY great, if the next version would also have a display as on the ESP32S3 (TFT LCD). Quality looks great, well packaged - Have no time to try it out right now.

I now have ordered 5 of these parts from Banggood. This is an incredible part. Very nice display, fast processor, enough RAM to write serious code and with WiFi, BLE interface this is the best arduino compatible part that is on the market now. I program this in Arduino, and have a 2000+ line program that fully exploits the device. For new Arduino projects, this is my preferred part.

I first got this part included with an enclosure for my Prusa 3D printer. I discovered the same part here at banggood, and ordered 2 pieces. They are good quality parts, that are small, have a clear and large display and have reasonable accuracy. I fully recommend this part. Shipment was very quick, so that is a nice bonus,

This is an amazing piece of hardware. This takes the Arduino universe to a whole new level. Banggood delivers this item quickly and I can definitely recommend them. Documentation on the part is not so good, see: http://www.datamot.com/BLOG.php
