Intro

This article is covering legacy mini-modules for development and prototyping, developed by xDevs.com back in 2008. There are no modules left in stock, and no new production batches planned. Purpose of this article is to support existing modules and customers who have them.

xDevs.com M16 – AVR ATmega development mini-module

Modules xDevs.com M16 targeted for prototyping and device testing. It is designed around DIP-40 size, and accepts ATMEL AVR mega16 or mega32 8-bit microcontrollers.

Specifications of xDevs M16

  • Footprint for RISC-microcontroller ATMEL AVR mega16 or mega32 in TQFP package
  • Fully compatible with DIP40 package pinout of ATmega16/32
  • SPI-connector for programming and ISP
  • Programmable UART, with access via USB VCP bridge SiLabs CP2103
  • Onboard crystal oscillator with 16MHz frequency
  • Nominal voltage 4.5-5.5 VDC, idle current consumption 1.1mADC
  • Power and user LED (attached to PA0 port)
  • Dimensions 55 × 17 × 20 mm
  • Rated operation temperatures – from 0°С to +85°С

Schematics of the module:

Revision 1

Revision 2

This revision is same schematics, just few minor tweaks on layout and white solder mask color.

xDevs.com A64 – ARM AT91SAM7S development mini-module

Modules xDevs.com A64 targeted for prototyping and device testing using ATMEL ARM7TDMI controllers. It is designed around DIP-40 size, and accepts ATMEL AT91SAM7S64, AT91SAM7S128 and AT91SAM7S256 32-bit ARM7 microcontrollers.

Specifications of xDevs A64

  • Footprint for RISC-microcontroller ATMEL AT91SAM7S* TQFP package
