Raspberry Pi Compute Module 4 Released!
-
Built on the same 64-bit quad-core BCM2711 application processor as Raspberry Pi 4, Compute Module 4 delivers a step-change in performance over its predecessors: faster CPU cores, better multimedia, more interfacing capabilities, and, for the first time, a choice of RAM densities and a wireless connectivity option.
You can find detailed specs here,
- 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU
- VideoCore VI graphics, supporting OpenGL ES 3.x
- 4Kp60 hardware decode of H.265 (HEVC) video
- 1080p60 hardware decode, and 1080p30 hardware encode of H.264 (AVC) video
- Dual HDMI interfaces, at resolutions up to 4K
- Single-lane PCI Express 2.0 interface
- Dual MIPI DSI display, and dual MIPI CSI-2 camera interfaces
- 1GB, 2GB, 4GB or 8GB LPDDR4-3200 SDRAM
- Optional 8GB, 16GB or 32GB eMMC Flash storage
- Optional 2.4GHz and 5GHz IEEE 802.11b/g/n/ac wireless LAN and Bluetooth 5.0
- Gigabit Ethernet PHY with IEEE 1588 support
- 28 GPIO pins, with up to 6 × UART, 6 × I2C and 5 × SPI
Compute Module 4 IO Board
The IO board provides:
- Two full-size HDMI ports
- Gigabit Ethernet jack
- Two USB 2.0 ports
- MicroSD card socket (only for use with Lite, no-eMMC Compute Module 4 variants)
- PCI Express Gen 2 x1 socket
- HAT footprint with 40-pin GPIO connector and PoE header
- 12V input via barrel jack (supports up to 26V if PCIe unused)
- Camera and display FPC connectors
- Real-time clock with battery backup

@salmanfaris at last they update their design. T
What you think on the updated connector. I felt like its more fragile and high chance for corottion issue due to humidity for long term use.
-
@Suhailjr But I think since it's not a plug and plug play system and it will laying on the PCB for the long term, it might be fine. for me, it's similar to the Intel Edison and the PICO-IMX7 System-on-Module

In this second edition of MakerCuriosity Podcast Series by MakerGram, we are discussing programming Microcontrollers using Python.
The discussion includes how exactly an interpreted language works on a Microcontroller?! Besides that, we have covered the pros and cons and when it is preferred to use Python on Microcontrollers when 95% of existing embedded code is written using either C or C++. Listen now and let us know your feedback and opinion!
Stay tuned till we meet with another exciting topic on next week!

Hi all,
I recently came across this post where they have shown photos printed on PCB in high resolution. I would like to know how to add this kind of photos to the silkscreen layers of the PCB in Eagle/Altium.
Adding such kind of photos will be attractive for beginners and also can be used for educational purposes too.
Please let me know in case anybody knows. -

The license of the https://dl.espressif.com/dl/package_esp32_index.json might be expired(If this is the reason you can't do anything but just wait until they re-activate the license)
If the page liecenceIt's good.

@abdultechguy999 usually https://dl.espressif.com/dl/package_esp32_index.json this works while installing through boards manager. But I faced the same issue some times. it might be due to a couple of reasons.
Bad Internet connectivity
The license of the https://dl.espressif.com/dl/package_esp32_index.json might be expired(If this is the reason you can't do anything but just wait until they re-activate the license)
I remember there is a way to install the board files offline by downloading from some github repos.
All the best.

Ok, then you need to check the LM2596 output current and voltage!
