SigmaStar SSC33x Camera SoCs are pin-to-pin compatible with Hisilicon Hi3516/Hi3518 processors

SSC336Q development kit

We’ve been writing a fair amount of posts about SigmaStar SSD201/SSD202D processors for smart displays in recent times. But the company also has various camera SoC’s with SSC333, SSC335, SSC336, SSC337, SS338, and SSC339 parts. Those processors feature one or two Cortex-A7 core, embedded RAM, as well as an optional AI accelerator called DLA (Deep Learning Accelerator). The chips manufactured using a 28nm or 22nm process, with the latter being used for parts with the AI accelerator. Most of the Sigmastar SCC33x processors also happen to be pin-to-pin compatible with HiSilicon Hi3516 or Hi3518 SoC that are found in a wide range of IP cameras. Let’s take SSC336D/SSC336Q processor as an example since it comes with the AI accelerator and we have a datasheet courtesy of linux-chenxing.com. SigmaStar SSC336D/SSC336Q camera SoC key features & specifications: CPU – Dual-core Arm Cortex-A7 processor @ 1 GHz with Neon and FPU Embedded Memory – Embedded 1Gbit (128MB) or 2Gb (256MB) 16-bit DDR3 memory […]

Allwinner D1 RISC-V processor SDK & Documentation

Allwinner D1 SDK

We published information about Allwinner D1 SBC and processor a few weeks ago. The news was pretty interesting as it’s the first RISC-V processor from the company, and one of the first affordable RISC-V SBC. But all we had at the time was hardware information from a leak, or rather from China-only Allwinner developer website. But now the company has added more information to its open-source development website with the release of documentation, now only in Chinese, as well as the Allwinner D1 Tina SDK. Eventually, there should be a better SDK via linux-sunxi community and some are already working on the Allwinner D1 SBC, but let’s try to get the SDK from Allwinner and build the code from source using the documentation. First, you’d need to register on Allwinner open-source website and click on signup. You’ll probably want to select Email registration. Now fill your username, select a country, enter a company name, password, and email. For the country, […]

Perf-V Beetle board features GAP8 multi-core RISC-V AI MCU

Perf-V Beetle board

GreenWaves Technologies introduced the GAP8 low-power RISC-V IoT processor optimized for artificial intelligence applications in 2018. The multi-core (8+1) RISC-V processor is especially suitable for image and audio algorithms including convolutional neural network (CNN) inference. The same year, the company launched the GAPUINO development kit that sold and (still sells) for $229 with QVGA camera and a multisensor board with four microphones, an STMicro VL53 Time of flight sensor, an IR sensor, a pressure sensor, a light sensor, a temperature & humidity sensor, and a 6-axis accelerometer/gyroscope. But there’s now a much more affordable solution to evaluate GAP8 multi-core RISC-V MCU with PerfXLab Perf-V Beetle board. Perf-V Beetle board specifications: MCU – GAP8 IoT Application Processor with 8x RISC-V compute cores, 1x RISC-V fabric controller core delivering up to 200 MOPS at 1mW and >8 GOPS at a few tens of mW System Memory – 64 Mbit SPI SRAM (LY68L6400SLIT) Storage – 128 Mbit SPI flash  (WS25Q128FVSIG) Audio – 4x […]

LoRa E5 development board

The LoRa-E5 STM32WL module we covered last month can now be found in two LoRaWAN development kits from Seeed Studio with the ultra-compact LoRa-E5 mini board, and the Arduino UNO shaped LoRa-E5 board with more I/Os. Both boards support the LoRaWAN protocol with global frequencies and can achieve a transmission range of up to 10 km with ultra-low power consumption. LoRa-E5 and LoRa-E5 mini specifications: LoRa connectivity LoRa-E5 modules based on STM32WLE5JC SoC with Arm Cortex-M4 MCU @ 48 MHz with 256 KB flash memory, 64 KB SRAM, SX126x LoRa radio Modulations – LoRa, (G)FSK, (G)MSK, BPSK Operating frequencies – 868/915MHz (EU868, US915, AU915, AS923, KR920, IN865) Output power – up to +20.8 dBm at 3.3V Rx sensitivity – -116.5 dBm to -136 dBm Protocol – LoRaWAN SMA-K and IPEX antenna connectors USB – 1x USB Type-C port for power and programming I/Os LoRa-E5 mini – 2x 12-pin through-hole and castellated headers with GPIO, UART, ADC, SPI, I2C, etc. LoRa-E5 […]

SigmaStar SSD201/SSD202 powered 4G LTE industrial gateway made to run mainline Linux

SSD202 gateway board

SigmaStar SSD201 is a dual-core Cortex-A7 processor with 64MB RAM onchip that is designed for smart HD displays. We’ve previously seen it in Industio 7-inch smart display running Linux, but if you want to modify anything you’d need sign an NDA before getting the SDK. Luckily there’s an open-source community named linux-chenxing that aims to bring mainline support to those low-cost SigmaStar processor to mainline, the same way linux-sunxi is working on Allwinner processors. Daniel Palmer noticed MYZR recently launched GW300 4G LTE industrial gateway with specifications that looked familiar. GW300 specifications from manufacturer’s website: Processor – Arm Cortex-A7 dual-core processor @ 1.2GHz Memory – 64MB RAM Storage – 128MByte Flash Connectivity – Ethernet and 4G LTE with high-gain antenna Serial – RS485/ RS232 via 5-pin terminal block Misc – RTC Power Supply – 12V to 24V DC input Dimensions – 127.7 x 87.5 x 30 mm Temperature Range – -20°C to +75°C The gateway runs Linux and supports ModBus […]

Getting Started with Raspberry Pi Pico using MicroPython and C

Raspberry Pi Pico Blink LED

Raspberry Pi Pico board was just launched last Thursday, but thanks to Cytron I received a sample a few hours after the announcement, and I’ve now had time to play with the board using MicroPython and C programming language. I went to the official documentation to get started, but I had to look around to achieve what I wanted to do, namely blinking some LEDs, so I’ll document my experience with my own getting started guide for Raspberry Pi Pico using a computer running Ubuntu 20.04 operating system. The instructions will be similar for Windows and Mac OS. Preparing the hardware In theory, we could just get started with the board alone, but since I got some headers with my board, I also took the opportunity to try out Pine64 Pinecil soldering iron powered by MINIX NEO P2 USB-C power supply. The soldering iron worked great for about one minute, and then I started to have problems with soldering… Looking […]
