$2 MXCHIP EMC3080 WiFi and Bluetooth LE IoT module integrates Cortex-M33 MCU

MXCHIP EMC3080 Cortex-M33 WiFi & Bluetooth-IoT module

While nowadays most people from the maker community are working with ESP8266 or ESP32 modules or boards for IoT projects requiring Bluetooth LE and/or WiFi connectivity, we’ve also covered some low-cost alternatives such as Bouffalo Labs BL602 or Realtek RTL8710. MXCHIP EMC3080 module offers yet an alternative with 2.4 GHz 802.11 b/g/n WiFi and Bluetooth LE 4.2/5.0. Where it differentiates against other solutions is that it features a more secure Cortex-M33 core clocked at 100 MHz, as found in UNISOC V5663 and Ameba RTL8722DM wireless SoCs, but still getting a fairly low price tag of $2.35 on Seeed Studio, which drops to $2.10 per pieces for orders of 10 or more units. MXCHIP EMC3080 module specifications: MCU – MX1300CF Cortex-M33 processor at up to 100 MHz with 256KB SRAM, 2MB XIP flash, 384 or 512 bytes OTP memory Connectivity WiFi 802.11 b/g/n 1T1R WiFi @ 2.4GHz Single Frequency HT20 support […]

MXCHIP EMW3060 WiFi IoT module sells for less than $2


Over the last few years, we’ve seen several Arm based WiFi IoT modules trying to compete with Tensilica based ESP8266 including Pine64 PADI IoT Stamp and Air602 WiFi IoT modules with similar functionalities and price (around $2) as the Espressif modules. I have not seen many projects with any of those Arm based wireless modules, likely because Espressif Systems software ecosystem is mature, and it’s hard to compete for new entrants. Nevertheless there’s a new Arm WiFi IoT module, not based on Cortex-M core, but instead, MXCHIP EMW3060 is equipped with an older ARM9 core, 256KB RAM, and 2MB flash, and sells for just $1.79 on Seeed Studio in single quantity. The price further drops to $1.55 per unit if you order 50 pieces or more. MXCHIP EMW3060 WiFi IoT module specifications: SoC ARM9 core clocked at 120 MHz System Memory – 256KB SRAM Storage – 2MB flash Connectivity – […]

MXCHIP EMW3165 is an $8 CE/FCC Certified WiFi Module with an STM32F4 Cortex M4 MCU

A few months ago, Seeed Studio started selling MXCHIP EMW3162 Wi-Fi module with a STM32F2 Cortex M3 MCU clocked at 120Mhz for $9.95. It’s more capable than ESP8266 modules but also around 3 times more expensive. The company has now launched another WiFi module called MXCHIP EMW3165 with an STM32F4 Cortex M4 MCU @ 100 MHz, FCC certification, and listed for $7.95. EMW3165 module specifications: MCU – STMicro STM32F411CE ARM Cortex M4 micro-controller @ 100 MHz with 512KB flash, 128KB RAM, DSP, and FPU Storage – 2MB SPI flash Wi-Fi connectivity 802.11b, 802.11g, 802.11n (single stream) WEP, WPA/WPA2 PSK/Enterprise [email protected]; [email protected]; [email protected] Receiver Sensitivity – 87 dBm Station, Soft AP and Wi-Fi direct Support EasyLink On-board PCB antenna (EMW3165-P model) or IPEX connector for external antenna (EMW3165-E model) CE & FCC compliant Peripherals: 22 GPIOs USART, I2C ADC, DAC Timer/PWM JTAG/SWD debug interface Connectors – 1×20 + 1x 21 half-through […]

MXCHIP EMW3162 is a $10 Low Power Wi-Fi Module for IoT Applications

You can’t beat ESP8266 Wi-Fi modules on price to add Wi-Fi to your IoT projects, but Hackaday found a new Wi-Fi module by Shanghai MXCHIP Information Technology that sells for $10 on Seeed Studio or Amazon US, that should be better suited to battery operated project thanks to a lower power consumption. EMW3162 also features a more powerful STM32F205 cortex M3 micro-controller, as well as more I/Os than ESP8266. Specifications for EMW3162 Wi-Fi module: MCU – STM32F2 Cortex M3 MCU @ 120 MHz with 128KB RAM, 1MB flashOn Wi-Fi connectivity 802.11b, 802.11g, 802.11n (single stream) on channel 1-14 @ 2.4GHz WEP, WPA/WPA2 PSK/Enterprise (hardware encryption) Transmit power: [email protected]; [email protected]; [email protected] MIN Receiver Sensitivity: -96 dBm Max Data rate: [email protected]; [email protected]; [email protected] HT20 Wi-Fi modes: Station, Soft AP and Wi-Fi direct Advanced 1×1 802.11n features: Full/Half Guard Interval, Frame Aggregation, Space Time Block Coding (STBC), Low Density Parity Check (LDPC) Encoding […]
