ESP32-PICO-KIT v4 Board Based on ESP32-PICO-D4 SiP Now Available for $10

A little while ago, I received a bunch of ESP32 PICO Core development boards which were based on Espressif Systems ESP32-PICO-D4 system-in-package with ESP32, 4MB SPI Flash, and other components. The advantage of such chip is that is requires less external component, and allows for smaller designs. For example, the boards I received would leave two row of pin on each side of the board, while most other ESP32 boards will only expose one row on each side. I used the board to play with Micropython ESP32 port, and later-on when I launched a giveaway of 8 of the boards, I found out the name had changed to ESP32-PICO Kit, with the documentation listing v3 with all pins connected to male headers, and v4 with 6-pin not connected to a male header as shown in the photo below. Both versions of the board also have a different pin layout. But […]

SAMA5D2 Based SiPs Combine ARM Cortex-A5 Processor With Up to 128MB DDR2

Atmel SAMA5D2 ARM Cortex-A5 processor was released about two years ago with extended temperature range and lower power consumption compared to previous SAMAD5 processors, with the new SoC still targeting industrial Internet of Things (IIoT), wearables and point of sale applications. In recent years, we’ve seen companies packing main components into systems-in-package (SiP) with products such as Octavo Systems OSD3358 and Espressif Systems ESP32-PICO-D4 with integrate an existing processor with memory, storage, and/or PMIC. Microchip (previously Atmel) has now done the same for their SAMA5D2 processors with SiPs combining the Cortex A5 SoC with DDR2 memory. Four SAMA5D2 SiPs have been launched: ATSAMA5D225C-D1M based on ATSAMA5D22C MPU with extra SD/SDIO, QSPI, FLEXCOMs (2x), I2S, and timers (2x) and: 128 Mb (16 MB) DDR2 DRAM 90 Peripheral I/Os 196 BGA Package Designed for RTOS/bare metal development ATSAMA5D27C-D5M based on ATSAMA5D27C MPU with: 512 Mb (64 MB) DDR2 DRAM 128 Peripheral I/Os […]

$25 PocketBeagle is a mini BeagleBone Board based on Octavo OSD3358-SM SiP

Earlier this year, Qwerty Embedded designed PocketBone board, an Eagle & KiCad open source hardware board software compatible with BeagleBone, but much smaller and based on Octavo OSD3358 system-in-package. This was never an official BeagleBoard.org board, and AFAIK it was not made broadly available. But the BeagleBoard foundation has now introduced PocketBeagle with a similar form factor, but based instead on the latest Octavo OSD3358-SM SiP that embeds TI Sitara AM3358, 512MB RAM, a PMIC, and various passive components into a 21×21 package, and exposing more I/Os thanks to 72 through holes. PocketBeagle board specifications: SiP (System-in-Package) – Octavo Systems OSD3358-SM with TI Sitara AM3358 ARM Cortex-A8 processor @ up to 1 GHz,  PowerVR SGX530 GPU, 2x PRU, ARM Cortex-M3 for power and security management functions 512MB DDR3 800 MHz 4kB I2C EEPROM TPS65217 PMIC + LDO with integrated 1-cell LiPo battery support Storage – micro SD slot USB – […]

ESP32-PICO-D4 System-in-Package Combines ESP32, 4MB SPI Flash, a Crystal Oscillator, and Passive Components

Espressif Systems has revealed another ESP32 variant, but this time it’s not an SoC, but a 7x7mm system-in-package (SIP) that comes ESP32 dual core processor, a 4MB  SPI flash, a crystal oscillator and various passive components, so that you don’t need to include those in your design, and create an ultra-compact PCB for wearables and other space-constrained applications. ESP32-PICO-D4 SiP specifications: SoC – ESP32 with two Tensilica LX6 cores, 448 KB ROM, 520 KB SRAM (inc. 8KB RTC memory), 1kbit eFuse On-module Flash – 4MB SPI flash Connectivity WiFi – 802.11 b/g/n/e/i (802.11n up to 150 Mbps) Bluetooth – Bluetooth V4.2 BR/EDR and BLE specification; ; class-1, class-2 and class-3 transmitter; Audio: CVSD and SBC SIP Interfaces SD card, UART, SPI, SDIO, LED PWM, Motor PWM, I2S, I2C, IR GPIO, capacitive touch sensor, ADC, DAC, LNA pre-amplifier Sensors –  On-chip Hall sensor & temperature sensor Clock – On-module 40 MHz crystal […]

CHIP Pro is a $16 WiFi and Bluetooth 4.2 System-on-Module Powered by a $6 GR8 ARM Cortex A8 SIP

Next Thing CHIP board and corresponding PocketCHIP portable Linux computer have been relatively popular due to their inexpensive price for the feature set, as for $9, you’d get an Allwinner R8 ARM Cortex A8 processor, 512MB flash, 4GB NAND flash, WiFi & Bluetooth connectivity, and plenty of I/Os, which made it very attractive for IoT applications compared to other cheap boards such as Raspberry Pi Zero and Orange Pi One. The first board was mostly designed for hobbyists, but  company has now designed a new lower profile system-on-module called CHIP Pro based on Next Thing GR8 SIP combining Allwinner R8 SoC with 256MB DDR3 RAM that can be used for easy integration into your own hardware project. While the original CHIP board exposed full USB ports and interface for video signal, the new CHIP Pro is specifically designed for IoT with the following specs: SIP – Allwinner R8 ARM Cortex […]

Setting a VoIP SIP user agent with Embedded Linux

This is a guest post by Leonardo Graboski Veiga, working for Toradex. Introduction This article’s main goals are: to cross-compile the PJSIP libraries and the PJSUA API reference implementation; deploy it to the target system; give an overview about the SIP protocol; and explore the reference implementation features, regarding audio only. For this purpose, a Computer on Module (CoM) from Toradex was chosen in the following configuration: Colibri iMX6DL* + Colibri Evaluation Board. The evaluation board and CoM are displayed in Figures 1 and 2, respectively.   VOIP or Voice over IP, is a term designed to refer to a set of methods and technologies targeted for the implementation of telephony services over the Internet. For the purpose of this article, the scope will be limited to the use of a reference implementation built upon the SIP communication handling protocol by means of the PJSIP libraries and PJSUA2 API. If […]

OSD3358 SiP Integrates TI Sitara AM3358 SoC, Memory, PMIC, LDO and Passive Components into a Single BGA System-in-Package

Octavo Systems has created a BeagleBone Black reference design that’s exactly like the original board, except for one detail: It’s based on the company’s OSD3358 system-in-package (SiP) that combine Texas Instruments AM3358 Cortex A8 processor with up to 1GB RAM, TI LDO and PMIC, and over 140 passive components into a single 400-ball BGA package. The only three other main components on the reference design are the eMMC flash, Ethernet transceiver and HDMI framer. Key specs of OSD3358 SiP: Texas Instruments AM335x (AM3358 or AM3352) Cortex A8 processor @ 1 GHz 256MB, 512 MB or 1GB DDR3 memory Texas Instruments TPS62217C PMIC Texas Instruments TL5209 LDO Over 140 passive components Package – 400 1.27mm pitch BGA – 27 x 27 mm package size Temperature Range – Base version: 0 to 85°C; Industrial version: -40° to 85° C Some of the advantages of a SiP package over using multiple chips include faster […]

Mediatek Unveils MT2523 SiP for GPS Enabled, Bluetooth LE Wearables

Silicon manufacturers are starting to launch ever more integrated solutions specifically designed for wearables, and after Samsung S3FBP5A bio-processor unveiled a few days ago, MediaTek has launched MT2623 ARM Cortex M4 System-in-Package (SiP) with GPS, Bluetooth LE, and a MIPI DSI interface. Other details are sparse but here’s what the company disclosed for MT2523: MCU core – ARM Cortex M4 GPU – 2D accelerator supporting true colors, per-pixel alpha channel, anti-aliasing fonts, and 1-bit index color to save memory. Connectivity – Dual-mode Bluetooth Low Energy and GPS Display – MIPI DSI and serial interfaces Integrated PMU Battery Life – More than a week (typical) The SiP’s printed circuit board area is said to be 41% percent smaller than competitors’ solutions.
