@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

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

Seeed is currently counting down for the 10 year anniversary of the debut of Grove . In the past 10 years, we have seen many wonderful projects created by Grove from our user and community. We want to invite you to join us to celebrate the 10 year anniversary of Grove 🤩.

In the Grove 10 Years Celebration, we’d like to collect the stories of “Grove with You”, which we want to invite our users to share their stories they have with Grove products.

=> What project you’ve made out of Grove?
=> What is your favourite Grove?
=> which one was the first Grove you’ve purchased?

Seeed encourages you to post and share photos, videos, stories of Grove in the Seeeed Forum, or any other platforms below that you’d like to use.

The following ways to find us, and tag #grove10 to share the project with us!

Twitter (@seeedstudio) Instagram (@seeedstudio) or simply email your project to grove10@seeed.cc

Feel free to be creative in documenting your projects–we will be selecting top 10 most “Grovy” winning entries from the submissions, and the winners will receive a $100 Grove Surprise Pack as a special gift.

Looking forward to seeing your projects! 🥳

@kowshik1729 I think that might not get since the platform is not opensource! but they provided everything you need to develop a system with that.

@kowshik1729 if you are more into ML take a look at the Jetson nano module, it's come with 4GB and 2GM Ram with 128-core NVIDIA Maxwell GPU and Quad-core ARM A57 CPU

@kowshik1729 I agree with what @kksjunior mentioned above, you can utilize the SoM, SoP's for your design, listing some of them.

1. Artemis Module - Low Power Machine Learning BLE Cortex-M4F
   If you are looking for SoC that can run ML, check the Artemis or nRF52840 .

2. OSD335x-SM System-in-Package, Smallest AM335x Module
   The OSD335x-SM is the smallest Texas Instruments AM335x module. It integrates the TI Sitara ARM Cortex-A8 AM335x processor, DDR3 memory, TPS65217C PMIC, TL5209 LDO, all the needed passives, and 4KB of EEPROM into a single BGA package. At 21mm X 21mm, it is 60% smaller than the discrete components and 40% smaller than the OSD335x.

@kowshik1729 If you are using an external high-speed switch, there is only one one clock generator for both wifi and BLE and the high-speed switch you mentioned is Ultra-Wideband (UWB) 3–8 GHz from its datasheet

you also check this solution that I shared in the previous post.

@salmanfaris said in BT and WiFi Dual Core simultaneous operation using ESP32?:

There is a special option called “Software controls WiFi/ Bluetooth coexistence” it can control the ESP32's Bluetooth and Wi-Fi coexistence using software, more details: https://www.espressif.com/sites/default/files/documentation/ESP32_FAQs__EN.pdf

Hi @Richu-Bini, The Uart Baud Rate Register (UBRR) is used to set the clock for the UART shift registers and For standard crystal and resonator frequencies, the most commonly used baud rates for asynchronous operation can be generated by using the UBRR settings provided by the AVR Datasheet: AVR306: Using the AVR USART on tinyAVR and megaAVR devices

And you can find the equation from the datasheet to calculate the UBRR values depends on the clock source it has.

more details at the AVR306: Using the AVR USART on tinyAVR and
megaAVR devices
