PICO-IMX8MQ Module
The development kit contains a PICO-IMX8MQ13-R20-E16-9377 module. As with all TechNexion PICO modules, this module also has guaranteed 12-year availability.
The module is certified in European Union (CE, RED, and ETSI), United States (FCC), Japan (TELEC), Canada (IC) and Australia/New Zealand (RCM).
Processor
The module is based on NXP i.MX8M Quad application processor which contains four 64-bit, Armv8-A Cortex A53 cores clocked at 1.3GHz and one Cortex M4F core clocked at 266MHz. The Cortex-A53 cores can be powered off while the low power Cortex-M4 subsystem performs real-time system monitoring. The cortex-A53 core is the successor of Cortex-A7 but with a performance similar to Cortex-A9.
The module is based on NXP i.MX8M Quad application processor. It contains four 64-bit, Armv8-A Cortex A53 cores clocked at 1.3GHz and one Cortex M4F core clocked at 266MHz.
The processor is targeted for applications in video and audio streaming, voice control, voice assistants and human-machine interface (HMI) solutions. For this kind of application the processor offers:
● Two independent display interfaces, up to 4Kp60 resolution on the HDMI 2.0a output and 1080p60 resolution on the 4-lanes MIPI-DSI.
● Hardware acceleration for video playback 4Kp60 HEVC/H.265 main and main 10 decoder, 4Kp60 VP9 decoder, 4Kp30 AVC/H.264 decoder.
● Two 4-lane MIPI-CSI for cameras
● 20 audio in/out 32-bit channels with sampling frequency up to 384 KHz with DSD512 support.
RAM and Storage
The module contains 2GB LPDDR4 RAM and 16GB eMMC 5.1 chip which supports 200MHz DDR mode. Bus width is 8-bit, so theoretical transfer speed is 400MB/s which is far more than the currently available industrial microSD cards can provide. High-performance Apacer H1-M industrial microSD, SD 3.0 card, for example, supports SDR104 mode with clock frequency 208MHz. Bus width is 4-bit, so the theoretical transfer speed is 104MB/s.
Wi-Fi and Bluetooth
PICO-IMX8M module uses Qualcomm Atheros QCA9377-3 based TechNexion PIXI-9377 module. It provides Wi-Fi 802.11 a/b/g/n/ac and Bluetooth 4.1 (BR+EDR+BLE). The model works as a Wi-Fi client, ad hoc, access point, hot spot and in the concurrent mode (client and AP simultaneously). PIXI-9377 works in the ambient temperature range of -40…85°C.
Environment and Variants
Standard modules are available for 0…60°C ambient temperature range. Modules for -20…70°C and -40...85°C are available upon request, MOQ is in the order of hundreds of pieces. Different module variants are available, please see our e-shop.
Compatibility with PICO-IMX6, IMX7 Modules
Board to board connector pinout is not compatible with PICO-IMX6, IMX7 modules so it is not possible to use PICO-IMX8M with HOBBIT, NYMPH, DWARF or PICO-PI-GL (FL) carrier boards. At the present time, PICO-IMX8M is compatible only with the PICO-PI-8M carrier board.
Connectors contain:
● USB 2.0 Host , USB 2.0 OTG
● HDMI, HDMI I2C, MIPI DSI 4-lane, 2xMIPI CSI 4-lane
● RGMII, PCIe [x1]
● SDIO
● 2xI2S, 2xUART, SPI (MISO, MOSI, CLK, SS0, SS1), 4xPWM, 2x I2C, 10 GPIO
PICO-PI-8M Carrier Board
PICO-PI-8M small dimension and available interfaces allow using the board for development, but also for integration into the end product. Board allows set boot source for PICO-IMX8M module from eMMC on module, microSD on carrier board or through USB OTG (serial download mode).
