LinkIt A-Core Packs Mediatek MT2502A SoC into a Tiny Module for Wearables

LinkIt ONE is a development board based on Meditak MT2502A SoC for wearables, and developed by SeeedStudio. With GPS, Wi-Fi, and GSM/GPRS connectivity, and a LiPo battery, it’s great to experiment IoT or wearable applications, but if you plan to launch an actual product, it could be nice to have a module, and built a baseboard around it. That’s exactly what SeeedStudio is working with LinkIt A-Core module. LinkIT A-Core module specifications: SoC – Mediatek MT2502AV ARM7 SoC @ 260 MHz with 32MB PSRAM and 32MB Flash on-chip. External Storage – 16M external Flash (MX25U12835F) Cellular Connectivity – GSM/GPRS quad-band 850/900/1800/1900MHz with RF7198 RF transmitter. Connectivity – Bluetooth 2.0 / 2.0 EDR / 4.0, GPS compatible GPS/GNSS (requires external GPS module) Expansion – 48 general purpose digital I/O Power supply: DC 3V~4.2V Power Consumption – > 3mA Dimensions – 19x23x2 mm The module is still in development, and the company welcomes comments in their announcement post.

Fernvale Open Source Hardware IoT Board Based on Mediatek MT6260 SoC with GSM Connectivity

Andrew Huang (Bunnie), an hardware engineer, known for hacking the original XBOX, and more recently for Novena open source laptop, has decided it could be interesting to reverse-engineer Mediatek MT6260 processor, as in China, it’s difficult to get documentation, SDK, and tools if you don’t commit to purchase X chips, where X is a rather large number. He and others also checked whether their work could be open sourced legally, and assert their “fair use” rights to reverse-engineer hardware and firmware. And so Fernvale project was born both as a technical challenge and to make a point. MT6260 is a $3 ARM7EJ-S processor clocked at 364 MHz with 8MB built-in RAM, interfaces such as I2C, SPI, PWM, UART, as well as LCD and touchscheen controller, and audio codec, battery charger, USB,  Bluetooth, and GSM support, which make the $6 Atmel MCU used in Arduino board look expensive. The main differences is that Atmel provides proper documentation to anyone who can […]

Getting Started with LinkIt ONE Development Kit for Wearables & IoT

After going through WRTnode Quick Start Guide, it’s now time to play with LinkIt ONE, the IoT development board from Mediatek designed by Seeed Studio. LinkIt ONE is the first Hardware Development Kit (HDK) for Mediatek LinkIt, so there may be a LinkIt TWO, and/or other hardware platforms in the future. LinkIt ONE specifications Let’s quickly go through the specifications first: Processor – Mediatek MT2502A (Aster) ARM7 EJ-STM processor @ 260 MHz System Memory – 4 MB Storage – 16MB Flash for firmware + micro SD slot shared with SIM slot for up to 32GB additional storage Connectivity: Wi-Fi – 802.11 b/g/n (MT5931) with external antenna Bluetooth – BR/EDR/BLE(Dual Mode) GPS – Mediatek MT3332 with external antenna GSM/GPRS – 850/900/1800/1900 MHz band, Class 12 GPS with external antenna Audio – 3.5mm headphone jack (including mic support) – Support for MP3, AAC, and AMR codecs. Serial – Software Serial (Serial), and Hardware Serial (Serial1, D0 & D1) Expansion Headers Arduino UNO […]

More Details on Mediatek MT2502 Aster SoC and Linkit Platform for Wearables (Video)

Last month, Mediatek announced their Mediatek MT2502 SoC for wearables, codenamed Aster, as well as the Linkit development platform targeting the developer’s community. But at the time they did show the actual hardware, and thanks to Charbax we know have more interesting details about Aster and Linkit. First they compare a design based on Aster to Samsung Galaxy Fit wearable band, and show why it uses less space, will cost less, and they claim  over twice the battery life. Simple and smaller design (~36% reduction in size) Aster solution – MT2504 (6.2 x 5.4 mm) plus all required resistors, capacitors and inductors require 89.97 mm2 Galaxy Fit – MCU. Bluetooth Transceiver,  external memory, a linear charger, and all required resistors, capacitors and inductors require 140.97 mm2 Battery life – Samsung Galaxy Fit is supposed to last between 1 and 1.5 days on a charge, whereas devices based on Aster should last about 4 days on a charge during regular usage. This is […]
